SECTION 1: ELECTRICAL THEORY & FUNDAMENTALS (Questions 1-50)
, Page 2 of 98
1. The unit of measurement for electrical current is the:
A) Volt
B) Ohm
C) Ampere
D) Watt
Rationale: Amperes (amps) measure electrical current, which is the rate of electron flow
through a conductor. Volts measure electrical potential or pressure, ohms measure resistance to
current flow, and watts measure electrical power.
2. According to Ohm's Law, the formula for calculating voltage is:
A) V = I / R
B) V = I × R
C) V = R / I
D) V = P × I
Rationale: Ohm's Law states that Voltage (V) = Current (I) × Resistance (R). This is the
fundamental relationship in electrical circuits. Current is inversely proportional to resistance
when voltage remains constant.
3. 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 3 of 98
Rationale: According to Ohm's Law (I = V/R), current is inversely proportional to resistance.
When resistance increases and voltage remains constant, current decreases. This is a
fundamental principle used in troubleshooting electrical circuits.
4. The formula for calculating electrical power is:
A) P = I × R
B) P = V × I
C) P = V / R
D) P = I / R
Rationale: The power formula is P = V × I (watts = volts × amperes). This relationship is
fundamental for calculating electrical power in both DC and AC circuits. For resistive loads, this
can also be expressed as P = I² × R or P = V²/R.
5. What is the total resistance of two 10-ohm resistors connected in series?
A) 5 ohms
B) 10 ohms
C) 20 ohms
D) 100 ohms
Rationale: In a series circuit, resistances add together: R_total = R1 + R2 = 10Ω + 10Ω = 20Ω.
Series connections are common in many electrical applications, including some control circuits
and heating elements.
6. What is the total resistance of two 10-ohm resistors connected in parallel?
A) 5 ohms
, Page 4 of 98
B) 10 ohms
C) 20 ohms
D) 100 ohms
Rationale: In a parallel circuit, the reciprocal of total resistance equals the sum of reciprocals:
1/R_total = 1/10 + 1/10 = 2/10, so R_total = 5Ω. Parallel connections reduce overall resistance
and are used in many branch circuit applications.
7. In a series circuit, how is voltage distributed?
A) Voltage is the same across all components
B) Voltage divides proportionally across components
C) Voltage is zero across all components
D) Voltage doubles across each component
Rationale: In a series circuit, voltage divides proportionally across components based on their
resistance values. The total voltage equals the sum of individual voltage drops. This principle is
essential for understanding voltage drop calculations.
8. In a parallel circuit, how is current distributed?
A) Current is the same through all branches
B) Current divides proportionally through branches
C) Current is zero through all branches
D) Current doubles through each branch
