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 an Inductor | Inductors Work | symbol

When an electric current travels through an inductor, it stores energy in the form of a magnetic field. It is sometimes referred to as a coil, chokes, or reactor. The inductor is also a passive electrical element

An inductor is nothing more than a wire coil. It is often made out of a coil of conducting material, commonly insulated copper, wrapped around an iron core made of plastic or ferromagnetic material; consequently, it is known as an iron-core inductor.

What is an Inductor | Inductors Work | symbol

Inductors are measured in Henry is denoted by (L). Inside the coil of many inductors is a magnetic core composed of ferrite or iron, which is used to enhance the magnetic field and hence the inductance of the inductor.

When an electric current running through an inductor or coil changes, the time-varying magnetic field creates an e.m.f (electromotive force) or voltage in it, according to Faraday's law of electromagnetic induction. The rate of change of the electric current flowing through an inductor is exactly proportional to the induced voltage or e.m.f. across the inductor.

Inductance (L) is an inductor attribute that opposes any change in the amplitude or direction of current flowing through it. The greater the inductance of an inductor, the greater it is capacity to store electrical energy in the form of a magnetic field.

Inductors Work

In a circuit, an inductor resists changes in current flow through it by producing a voltage across it that is proportional to the rate of change of current flow. Consider the illustration below to see how an inductor works in a circuit.

A light, a coil of wire (inductor), and a switch are shown linked to a battery. When we remove the inductor from the circuit, the bulb lights up normally. The circuit operates entirely differently when an inductor is used.

However, because of the inductor behavior in the circuit, when we close the switch, the light glows brilliantly and then dims, and when we open the switch, the bulb burns brightly and then soon goes out. When a voltage or potential difference is put across an inductor, the electric current passing through it generates a magnetic field. According to Lenz's law, this magnetic field induces an electric current in the inductor with the opposite polarity.

This induced current caused by the inductor's magnetic field attempts to counteract any change in current, whether it be an increase or a reduction. The current can flow normally after the magnetic field is established.

When the switch is closed, the magnetic field around the inductor maintains current flow until the magnetic field decreases. Even if the switch is turned off, this current maintains the bulb lit for a short period of time.

In other words, the inductor may store energy in the form of a magnetic field and resist changes in the current running through it. As a result, the current flowing through an inductor cannot vary instantly.

Inductor Symbol

In the figure below, the schematic circuit symbol for an inductor is given.

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...

74HC165 Shift Register and your Arduino UNO

Today in this tutorial I'll explain to you how to control the 74HC165 parallel in serial out(PISO) shift register using your ARDUINO board. Here we used 74HC165 for increasing numbers of inputs of your ARDUINO board. Shift registers are often used for the purpose of saving pins on a microcontroller. Every microcontroller has a limited number of pins for general inputs and outputs (GPIO). Sometimes we have required more inputs and our controller does not provide such inputs at that time parallel in serial out(PISO) shift register is used to increase inputs. An 8-bit shift register needs 4 lines of a microcontroller. One pin to clock for data transfer, one for clock enable, one for shifting/loading/latching the bits, and one for serial data transfer. Here we used only 3 pins of microcontrollers. One pin for loading the bits, one pin to clock for data transfer, one pin to serial data transfer. In 74HC165 Clock enable pin is active low so we connect it to the ground. Two 74HC165 can be...

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...
