,SECTION 1: GENERAL ELECTRICAL THEORY AND FUNDAMENTALS (40 Questions)
Question 1
Which fundamental electrical quantity is measured in volts?
A) Resistance
B) Voltage
C) Current
D) Power

Correct Answer: B) Voltage
Rationale: Voltage is the electrical potential difference measured in volts.
It is the driving force that causes current to flow in a circuit.

Question 2
What does Ohm's Law state?
A) V = I × R
B) P = V × I
C) I = P × R
D) V = P / I

Correct Answer: A) V = I × R
Rationale: Ohm's Law states that voltage (V) equals current (I) multiplied by
resistance (R). This fundamental relationship governs electrical circuits.

Question 3
What is the formula for electrical power?
A) P = V × I
B) P = I × R
C) P = V / R
D) P = V² × R

Correct Answer: A) P = V × I
Rationale: Power (P) equals voltage (V) multiplied by current (I). This is the
basic power formula for DC circuits.

Question 4
What is the unit of electrical resistance?
A) Volt
B) Ampere


3

, C) Ohm
D) Watt

Correct Answer: C) Ohm
Rationale: The ohm is the unit of electrical resistance. One ohm is the resistance
that allows one ampere of current to flow when one volt is applied.

Question 5
What is the unit of electrical current?
A) Volt
B) Ampere
C) Ohm
D) Watt

Correct Answer: B) Ampere
Rationale: The ampere (amp) is the unit of electrical current, representing the
rate of flow of electric charge.

Question 6
What is the unit of electrical power?
A) Volt
B) Ampere
C) Ohm
D) Watt

Correct Answer: D) Watt
Rationale: The watt is the unit of electrical power, representing the rate of
energy transfer.

Question 7
What is the difference between AC and DC?
A) AC changes direction periodically; DC flows in one direction
B) AC flows in one direction; DC changes direction periodically
C) AC has higher voltage; DC has lower voltage
D) AC is used only in residential; DC is used only in commercial

Correct Answer: A) AC changes direction periodically; DC flows in one direction
Rationale: Alternating current (AC) reverses direction periodically, while direct
