SECTION 1: ELECTRICAL THEORY FUNDAMENTALS (Questions 1-50)
1. What is the unit of measurement for electrical current?
A) Volts
B) Ohms
C) Amperes
D) Watts
Correct Answer: C
Rationale: Amperes (amps) measure electrical current, the rate of electron flow through a conductor.
Volts measure electrical potential (pressure), ohms measure resistance (opposition to current flow), and
watts measure power (rate of energy consumption) .
2. What is the unit of measurement for electrical resistance?
, Page 3 of 201
A) Volts
B) Ohms
C) Amperes
D) Watts
Correct Answer: B
Rationale: Ohms (Ω) measure electrical resistance, which is the opposition to current flow in a circuit.
This relationship is defined by Ohm's Law (R = V/I) .
3. According to Ohm's Law, what happens to current when resistance increases while voltage remains
constant?
A) Current increases
B) Current decreases
C) Current remains the same
D) Current doubles
, Page 4 of 201
Correct Answer: B
Rationale: According to Ohm's Law (I = V/R), current is inversely proportional to resistance. When
resistance increases and voltage remains constant, current must decrease .
4. A 120-volt circuit draws 10 amps continuously for an emergency lighting load. What is the minimum
wattage consumed?
A) 12 watts
B) 120 watts
C) 1,200 watts
D) 2,400 watts
Correct Answer: C
Rationale: Power = Voltage × Current = 120V × 10A = 1,200 watts. This is the fundamental power
formula (P = V × I) .
