CFESA Electrical Practice Test Exam 2026
180 Practice Questions with Answers and Rationales
Section 1: Basic Electrical Theory (Questions 1-30)
1. Voltage is best defined as:
A) The movement of electrons through a circuit
B) The opposition to current flow
C) The potential difference or driving force of electrons between two
lines
D) The amount of energy used by a circuit
Correct Answer: C
,Rationale: Voltage is the electrical potential difference that drives
current through a circuit. It is measured in volts and represents the
"pressure" that pushes electrons to flow from negative to positive .
2. Current is measured in:
A) Volts
B) Ohms
C) Watts
D) Amps
Correct Answer: D
Rationale: Current is the movement of electrons through a circuit when
a difference of potential exists. It is measured in amperes (amps) .
3. Resistance is measured in:
,A) Volts
B) Amps
C) Ohms
D) Watts
Correct Answer: C
Rationale: Resistance is the impedance or opposition to the flow of
current. It is measured in Ohms (Ω) .
4. In a series circuit:
A) Voltage stays the same across all loads
B) Current divides across resistances
C) Current stays the same everywhere
, D) Total resistance is less than the smallest resistance
Correct Answer: C
Rationale: In a series circuit, current remains constant throughout the
circuit. Voltage divides across the resistances, and total resistance is
found by adding all resistances together .
5. In a parallel circuit:
A) Current stays the same everywhere
B) Voltage divides across the loads
C) Voltage stays the same across all loads
D) Total resistance is greater than the largest resistance
