  • 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.

  • 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

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.

  • What color is typically used for an equipment grounding
  • conductor? 2 / 3

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
