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 ...

Resistors in Series and Parallel connection

We're going to learn about resistors Series and parallel today. Electrical resistance, as we all know, is the resistance to current passage in an electric circuit. The resistance of a resistor restricts the passage of electrons in a circuit. A conductor is a person who acts as a guide for other people. Assume that there is no opposition. When we provide a voltage differential to the conductor, the electrons begin to travel through it.

Resistors in Series and Parallel connection

A negative current flow is a moving electron flow. An ammeter may be used to determine the amount of current flowing. We have a very high current because there is no resistance in the conductor to slow down the electrons; they are moving at full speed. Consider another conductor, but this one is equipped with a resistor. Apply the same amount of voltage as when electrons initially started to flow. Electrons have a second choice: they must pass through the resistor. What is the current reading on the ammeter? Because the electron flow is limited by the resistor, it is lower than the initial measurement. Let's try a different conductor with two series resistors. Both impediments must be passed by the current flow. As a result, the ammeter value is lower than before. Similarly, we may raise the resistance by connecting more resistors in series. A resistor is represented by this symbol. r1 is now the entire resistance.

The total resistance becomes r1+r2 when we add another resistor with r2 resistance. Let's add a third r3 resistor to the circuit. The entire opposition continues to rise. r1+ r2+ r3 is now the total resistance. As a result, the sum of the series resistors' individual resistances equals the overall resistance of the series resistors. Let's go back to the beginning. We already know that series resistors lower current. Assume that only the i1 current may pass through this resistor. The current ammeter value is now i1. What happens if two resistors with the same resistance are connected in parallel? Then connect them with the same voltage A total of i1 current can pass across each resistor. i1 + i1 = 2i1 is now the ammeter reading. The current has become stronger. 

This indicates that the overall resistance has lessened. We may lower the resistance by using parallel resistors. Take a look at this diagram. The voltage, resistance, and current between locations A and B are denoted by V, R, and I, respectively. It will transfer i1 current through an R1 resistor placed between locations A and B. Because there is no other path for current to go from point A to point B, the total current I equals i1. We can use Ohm's law to help us.

The letters v and R can be used to replace the letters i. On both sides, we may eliminate the word "v." This is what we're getting: Right. Let's add a parallel resistor to the r1 resistor. We may substitute v and R for I in situations like this. On both sides, we may eliminate the word "v." This is what we're getting: Right. Let's add a parallel resistor to the r1 resistor. This, for example. I2 current can flow via this new r2 resistor. From point a to point b, the current can take one of two paths. The sum of these two currents equals the total current. We may simplify the problem by utilizing Ohm's rule to replace the i. We can continue to add parallel resistors by adding more resistors in parallel. We may write an equation for 3 parallel resistors.

This is how we may construct an equation. The inverse of the overall resistance in a parallel resistor circuit is equal to the sum of the inverses of each individual resistor.

What is a Positive Temperature Coefficient (PTC) | Positive Temperature Coefficient Thermistor

PTC is an initial for Positive Temperature Coefficient PTC thermistors are resistors with a positive temperature coefficient, meaning their resistance rises as the temperature rises. PTC thermistors are classified into two types depending on the materials used, the structure of the device, and the production method. Solicitors are the earliest type of PTC thermistors, and they employ silicon as the semiconducting material. Because of their linear feature, they are employed as PTC temperature sensors.  The switching type PTC thermistor is the second category. The resistance-temperature curve of a switching type PTC thermistor is very nonlinear. When a switching type PTC thermistor is heated, the resistance initially decreases until a critical temperature is achieved. As the temperature rises above the critical point, the resistance rises substantially. This kind of PTC thermistor is commonly utilized in PTC heaters, sensors, and other applications. This second group includes polyme...

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...

Interfacing Push button switch with AT89S52 Microcontroller.

This tutorial is for beginners in the field of micro-controller. The purpose of this tutorial is to use of push-button switch with the micro-controller. It will be useful whenever a decision is to be made according to the press of a switch. Input/output devices are very critical components of an embedded system. The first input device we will study is the switch. It allows the human to input binary information into the microcontroller. Typically we define the Two-state, logic as true when the switch is pressed. logic false, when the switch is not pressed. A single pole single throw (SPST) switch has two connections. The switches are shown as open circuits in Figure 1. which is a normally open switch (NO), the resistance between the connections is infinite (over 1000 MΩ) if the switch is not pressed and zero (under 0.1 Ω) if the switch is pressed.  A switch has a two-state open state and a closed state. And the state of the switch is monitored by the microcontroller at a digital inp...
