• Transformers work on the principle of electromagnetic induction

• They are used to increase or decrease voltage levels in electrical circuits

• Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer

• Step-up transformers increase voltage levels, while step-down...read more

Vcb stands for Vacuum Circuit Breaker which is a type of electrical switch used for power distribution.

• Vcb is used to interrupt or break the flow of electrical current in a circuit.

• It uses vacuum as the arc quenching medium instead of air or oil.

• Vcb is commonly used in high voltage applications such as power plants and substations.

• It has several advantages over other types of circuit breakers such as low maintenance, h...read more

A diode is an electronic component that allows current to flow in only one direction.

• Diodes have two terminals: an anode and a cathode.

• When a voltage is applied to the anode, current flows through the diode.

• If the voltage is reversed, the diode blocks the current.

• Diodes are commonly used in rectifiers, voltage regulators, and signal limiters.
