1.
A radio repair technician measures voltage across a resistor and needs to calculate current. Which law
should be applied to determine the correct value?
, Page 2 of 91
A. Kirchhoff’s Law
B. Ohm’s Law
C. Faraday’s Law
D. Coulomb’s Law
Answer: B
Rationale: Ohm’s Law relates voltage, current, and resistance.
2.
While repairing a radio circuit, a technician notices no current flow despite voltage being present. What
is the most likely issue?
A. Short circuit
B. Open circuit
C. Overheating
D. Excess resistance
Answer: B
Rationale: Open circuits stop current flow.
3.
A technician uses a multimeter to measure resistance in a circuit. What must be done before taking the
measurement?
A. Increase voltage
, Page 3 of 91
B. Turn off power
C. Increase current
D. Add load
Answer: B
Rationale: Resistance is measured with power off.
4.
A capacitor in a radio circuit fails and causes signal distortion. What is the likely role of this component?
A. Amplification
B. Energy storage and filtering
C. Switching
D. Frequency generation
Answer: B
Rationale: Capacitors filter and store energy.
5.
A radio receiver produces weak signals due to antenna issues. What is the most likely cause?
A. Excess voltage
B. Poor antenna connection
C. High current
D. Low resistance
, Page 4 of 91
Answer: B
Rationale: Antenna connection affects signal strength.
6.
A technician identifies a burned resistor in a circuit. What is the most appropriate next step?
A. Ignore
B. Replace with correct value resistor
C. Increase voltage
D. Remove permanently
Answer: B
Rationale: Must replace with proper rating.
7.
A radio circuit uses alternating current. What distinguishes AC from DC in this context?
A. Constant direction
B. Periodic direction change
C. No voltage
D. No current
Answer: B
Rationale: AC changes direction periodically.
