Industrial VS Commercial VS Residential Electrical Installation

Hey, in this article we are going to see the comparison between Industrial, Commercial, and Residential Electrical installation. We will make compare with respect to types, procedure, cost, safety, equipment, and many other essential factors. First of all, let's know what is electrical installation. Electrical installation is a procedure to install electrical circuits, wirings, equipment, and machines. The electrical installation can be divided into three major parts - 1. Installing of electrical equipment or device or machine 2. Make electrical connection or wiring for them 3. Provide them proper voltage and power to operate them. These different types of electrical installation required different types of electricians and management. For example, commercial electrical installation requires commercial electricians, industrial electrical installation requires industrial electricians, and residential electrical installation requires residential electricians. We already published an ...

what is current

Today, we'll look at the fundamentals of electrical current. It may thus be characterized as a flow of electrical charge in basic words. to grasp the information of current, we must first grasp the concept of electrical charge. 

Each atom, which is the basic building unit of any substance, is made up of three main elements. The nucleus includes protons and neutrons, and the electron orbits around the nucleus. Now, by delivering a small amount of energy, the electron in the outermost orbit may now be readily pushed out of the atom.

These electrons, which are in the furthest orbit, contribute to the current flow. As a result, electrons have a negative charge while protons have a positive charge. Neutrons have no charge and are thus electrically neutral. As a result, charges of the same polarity tend to migrate apart from one another. Charges with opposing polarities are attracted to one another. The Coulomb is the unit of charge. The sign Q or q is used to represent it. When we discuss the electron charge, we sometimes use the symbol e to represent it.

One electron carries a charge of 1.6 x 10-19 Coulomb as a result of this. We need 4.28 x 1018 electrons to have one coulomb of charge, which is the inverse of this amount. So, in order to have one coulomb of charge, these many electrons must be charged. Now that we've grasped the notion of charge, let's move on to the concept of current. Let's pretend we have a length of copper wire. This copper cable is also carrying electrons. We also want to know how many electrons pass via this copper wire. So, with this copper wire A-A', let's select one reference point.

This is the copper wire's cross-section. Assume that 1 C of charge is flowing via this copper wire. We may state that the current flowing through this copper wire is 1 C/S if 1 coulomb of charge passes through this reference point in one second. 1 amp is also an option. As a result, the current is defined as the rate at which an electrical charge passes through this reference point. The ampere is the unit of the current measurement. It's represented by the letter I. Let's use the example of tap water to better grasp the notion of current. The volume of water that flows through the tap is determined by the pace at which water particles exit the tap.

The greater the pace at which particles emerge from the tap, the greater the water flow. Similarly, the larger the flow of current is, the faster this electrical charge or electrons move past this reference point. We may state that the flow of current is five amperes if 5 C of charge flows through this reference point in one second. So, in order for this charge to move, we need some type of energy. So, unless we supply some sort of energy or external force, these electrons or the electrical charges will not contribute to the flow of current.

So, let's put this energy to use by connecting it to this copper wire through an external battery. The electrons will be delivered to one end of the copper wire as a result of this battery. As a result, electrons in this copper wire that are free will be repelled by the negative charge produced by this battery. And these liberated electrons will go to the copper wire's opposite end. They will be drawn to the positive terminal of the battery at the opposite end of the copper wire. As a result, a flow of electrons from the negative to the positive direction is created.

As a result, electrons move from the negative to the positive terminal of the circuit. However, in electrical circuits, we usually take a current flow from the positive to the negative direction. So that's the traditional current flow. As a result, the conventional current flows from the circuit's positive to negative terminals. So, as we've mentioned, we'll need some form of energy to get this charge moving. A joule is a unit of measurement for energy. So, let's say we have one coulomb of charge, and we need the energy to transport it from the negative to the positive terminal. One joule equals one joule.

We may state that the potential difference between the positive and negative terminals is 1 volt if 1 joule of energy is required to transfer 1 cobalt charge from the negative to the positive terminal. So there you have it, a definition of voltage.

What is the Joule Thief Circuit and how does it work

A joule thief is a compact, low-cost, and easy-to-build self-oscillating voltage booster that is often used to drive small loads(3.3v 5mm LED). Other names for this circuit include blocking oscillator , joule ringer , and vampire torch . The circuit is a blocking oscillator variation that functions as an unregulated voltage boost converter. The output voltage is increased at the price of a larger input current draw, but the output integrated (average) current is reduced and the luminescence brightness is reduced. This joule thief Circuit uses a 1.2 V or 1.5 V single-cell electric battery to power LEDs. However, as the supply voltage reaches 3V, the LED begins to light. The theory of operation of a Joule thief circuit Joule Thief Circuit The joule thief circuit operates on a fairly basic basis. It operates by quickly switching the transistor. When the transistor is first switched off, a tiny amount of current flows via the resistor, primary winding, and base-emitter junction, assistin...

What is an electric fuse | Fuse resistance | Functions

To avoid a short circuit or device failure, an electrical fuse is a low melting point copper or other metal wire that breaks due to heat-induced by Overcurrent or excessive load. The flow of electric current warms up the items through which it passes. Electric water heaters, light bulbs, and irons are just a few examples of electric gadgets that make use of this phenomenon. It does, however, have certain downsides. For example, if this equipment becomes overheated, it may become damaged or even catch fire! In reality, the undesirable high electric currents harm not only these gadgets, but all of the appliances in our home. Any gadget can only withstand a certain quantity of electric current. If the current surpasses that limit, the device's components heat up, perhaps resulting in a fire! Is there a way to prevent this from happening? An "electric fuse" is a device that is used to prevent this from happening. It comes in a variety of forms and sizes. This is how it usuall...

Using the IR2110 high-low side driver - explanation and circuit examples

In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. Notice that the IR2110 comes in two packages – 14 pin through-hole PDIP package and the 16-pin surface mount SOIC package. Now let's talk about the different pins. VCC is the low-side supply and should be between 10V and 20V. VDD is the logic supply to the IR2110. It can be between +3V to +20V (with reference to VSS). The actual voltag...
