What is the function of a transformer in an electrical system?
Answer: Change voltage levels
A transformer steps voltage up or down using electromagnetic induction between coils.
Which material is the best conductor of electricity?
Answer: Copper
Copper is an excellent conductor due to its low electrical resistance and is widely used in wiring.
Ground fault protection is designed to protect against:
Answer: Unintended current paths to ground that can cause shock

A circuit breaker differs from a fuse in that a circuit breaker:
Answer: Can be reset after tripping
Unlike a fuse that must be replaced after opening, a circuit breaker can be manually reset.
What unit measures electrical resistance?
Answer: Ohm
Electrical resistance is measured in ohms (Ω), named after Georg Simon Ohm.
In the formula P = V × I, what does 'P' represent?
Answer: Power in watts
P = V × I is the power formula where P is electrical power measured in watts.
