Salcomp Manufacturing Utility & Maintenance Engineer Interview Questions and Answers

Q1. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more potential energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)

Q2. What is insulator
Ans. 
An insulator is a material that does not conduct electricity, heat, or sound.
• Insulators prevent the flow of electricity, heat, or sound.

• Common insulating materials include rubber, glass, plastic, and ceramic.

• Insulators are used to protect against electric shocks, prevent heat loss, and reduce noise transmission.

• Insulators have high resistance to the flow of electrons.
