1. What is the unit of electrical current?
a) Ohm
b) Volt
c) Ampere
d) Ampere
Rationale: Current is measured in amperes (A), representing the
rate of flow of electrons.
2. Which material is most commonly used as a conductor in
residential wiring?
a) Steel
b) Gold
c) Aluminium
d) Copper
Rationale: Copper provides low resistance, high conductivity,
and flexibility for wiring.
,3. Ohm’s law can be expressed as:
a) P = IV
b) V = IR
c) R = P/I
d) I = PR
Rationale: Ohm’s law states voltage equals current multiplied by
resistance.
4. The purpose of bonding is to:
a) Increase resistance
b) Reduce voltage
c) Ensure a low-impedance fault path
d) Insulate live parts
Rationale: Bonding creates a conductive path to allow
overcurrent devices to trip quickly.
5. A GFCI protects against:
a) Overcurrent
b) Ground faults
c) Overvoltage
d) Short circuits
Rationale: GFCIs detect imbalance between hot and neutral
indicating leakage to ground.
6. What color is typically used for an equipment grounding
conductor?
, a) Red
b) Blue
c) Green
d) Brown
Rationale: Green or green/yellow is standard for grounding
conductors.
7. The primary purpose of a fuse is to:
a) Protect people
b) Bond equipment
c) Protect conductors from overcurrent
d) Reduce voltage drops
Rationale: Fuses interrupt excessive current to prevent wire
overheating.
8. A device used to change AC voltage levels is called a:
a) Resistor
b) Transformer
c) Relay
d) Capacitor
Rationale: Transformers raise or lower AC voltages through
electromagnetic induction.
9. A circuit with only one path for current flow is a:
a) Parallel circuit
b) Series circuit
c) Combination circuit
