Pull-Up Resistor: What is it (And How Does It Work)?

What is a Pull-up Resistor? A pull-up resistor is used in electronic logic circuits to ensure a known state for a signal. It is usually used in combination with transistors and switches to ensure the voltage between ground and Vcc is actively controlled when the switch is open (similar to a pull-down resistor). It is … Read more

Grounding Conductor: What is it (And How Do You Calculate The Right Size)?

What is a Grounding Conductor? A grounding conductor is defined as a wire or conductor intentionally connected to the earth. The grounding conductor is commonly known as a “ground conductor” or “case ground.” In most cases, the ground wire is connected with a case or outer part of the electrical box, appliances, or tools. Hence, … Read more

Split Capacitor Motor: What is it (And How Does it Work)?

What is a Permanent Split Capacitor Motor? A permanent split capacitor motor (also known as a single value capacitor motor or PSC motor) is defined as a type of split-phase induction motor in which the capacitor is connected permanently. A split capacitor motor is an AC motor. It is a type of single-phase induction motor. … Read more

Fast Recovery Diode: What is it And How Does it Work?

What is a Fast Recovery Diode? A fast recovery diode (also known as a fast diode or fast switching diode) is defined as a semiconductor device with a short reverse recovery time. Because fast recovery diodes have a lower reverse recovery time than conventional diodes, they are better suited to high-frequency rectification applications. As fast … Read more

Series And Parallel Inductors (Formula & Example Problems)

What is an Inductor? An inductor (also known as an electrical inductor) is defined as a two-terminal passive electrical element that stores energy in the form of a magnetic field when electric current flows through it. It is also called a coil, chokes, or reactor. An inductor is simply a coil of wire. It usually … Read more

Shunt Resistor: What is it And How Does it Work?

What is a Shunt Resistor? A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of the electric current through the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving … Read more

Berry Type Transformer: What is it? (Diagram Included)

What is a Berry Type Transformer? A transformer with a core that looks like a spoke of the wheel is known as a berry type transformer (or “berry transformer” for short). According to the type of core, transformers can be classified into three types; Core type transformer Shell type transformer Berry type transformer Sometimes, a … Read more

Ohm’s Law: How it Works (Formula and Ohm’s Law Triangle)

What is Ohm’s Law? Ohm’s law states that the electrical current flowing through any conductor is directly proportional to the potential difference (voltage) between its ends, assuming the physical conditions of the conductor do not change. In other words, the ratio of potential difference between any two points of a conductor to the current flowing … Read more
