Q: What is the unit of measurement for electric current?

Ampere (Amp) — Current is measured in Amperes, representing the flow of electric charge.

Q: Which of the following is a safety device used in electrical circuits to protect against overcurrent?

Circuit breaker — Circuit breakers interrupt the circuit when excessive current flows, preventing damage.

Q: What is the purpose of grounding in an electrical installation?

To provide a low-resistance path to the earth for fault current — Grounding directs fault current safely to the earth, minimizing the risk of electric shock.

Q: Which of the following describes the relationship between voltage (V), current (I), and resistance (R) in a circuit?

V = I * R — Ohm's Law states that Voltage equals Current times Resistance.

Q: What does 'AC' stand for in electrical terms?

Alternating Current — AC stands for Alternating Current, which periodically reverses direction.
