Assistant Project Engineer Interview Questions and Answers for Freshers

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They are used to increase or decrease the voltage of an alternating current (AC) power supply

• Consists of two coils of wire, primary and secondary, wrapped around a magnetic core

• When AC current flows through the primary coil, it creates a magnetic field that induces a voltage in the s...read more

A transmission line is a specialized cable designed to carry high-frequency electrical signals with minimal loss of energy.

• Transmission lines are used to transmit electrical energy from one point to another.

• They are commonly used in power grids to transport electricity over long distances.

• Transmission lines can be made of various materials such as copper, aluminum, or fiber optic cables.

• The performance of a transmission line is affected by factors such as the length of the li...read more
