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...

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...
