Which set correctly represents the symbols for voltage, amperage, and resistance?
A. V, W, Ω
B. E or V, I or A, R or Ω
C. A, V, R
D. P, I, R
Correct Answer: B
Rationale: Voltage is represented by E or V, current (amperage) by I or A, and resistance by R or
Ω (ohms).
Watt’s Law explains the relationship between which three values?
A. Resistance, Current, Power
B. Watts, Amps, and Volts
C. Voltage, Resistance, Frequency
D. Current, Energy, Heat
Correct Answer: B
Rationale: Watt’s Law (P = VI) relates power (watts), voltage (volts), and current (amps).
In magnetism, opposite poles do what?
A. Repel
B. Neutralize
C. Attract
D. Rotate
Correct Answer: C
Rationale: Opposite magnetic poles attract each other, while like poles repel.
Which two parts of an atom attract each other in a 1:1 ratio?
A. Neutrons and electrons
B. Protons and neutrons
C. Protons and electrons
,D. Electrons and ions
Correct Answer: C
Rationale: Protons (+) and electrons (–) attract each other in equal numbers in a neutral atom.
The electrical flow in a circuit is known as:
A. Voltage
B. Resistance
C. Current
D. Power
Correct Answer: C
Rationale: Current is the flow of electric charge through a conductor.
If a 12V motor draws 4A, what is its resistance?
A. 2 Ω
B. 3 Ω
C. 4 Ω
D. 6 Ω
Correct Answer: B
Rationale: Using Ohm’s Law (R = V ÷ I): 12 ÷ 4 = 3 ohms.
If a blower motor has 2 Ω resistance and draws 5A, what is the voltage?
A. 7 V
B. 8 V
C. 10 V
D. 12 V
Correct Answer: C
Rationale: Using V = IR: 5 × 2 = 10 volts.
If a 12V trunk motor has 4 Ω resistance, how much current does it draw?
A. 2 A
B. 3 A
C. 4 A
D. 6 A
Correct Answer: B
Rationale: Using I = V ÷ R: 12 ÷ 4 = 3 amps.
Energy can be created or destroyed.
A. True
B. False
C. Only in circuits
, D. Only in magnets
Correct Answer: B
Rationale: According to the law of conservation of energy, energy cannot be created or
destroyed.
In AWG, which wire carries more current?
A. 10 gauge
B. 4 gauge
C. Both equal
D. Depends on voltage
Correct Answer: B
Rationale: Lower gauge numbers indicate thicker wires, which carry more current.
Gold and silver are the most common and cheapest conductors.
A. True
B. False
C. Only gold
D. Only silver
Correct Answer: B
Rationale: While highly conductive, gold and silver are expensive and not the most common
conductors.
If another leg is added to a parallel circuit, resistance and current will:
A. Both increase
B. Both decrease
C. Resistance decreases, current increases
D. Resistance increases, current decreases
Correct Answer: C
Rationale: Adding a parallel path lowers total resistance and increases total current.
In a series circuit, total resistance is the ______ of all resistor values.
A. Difference
B. Product
C. Average
D. Sum
Correct Answer: D
Rationale: In series circuits, resistances add directly together.
Anytime current flows through a conductor, it creates a:
A. Voltage drop
