Answers & Detailed Explanations |
2026/2027
1. Definition of series circuit
A. Current flows in multiple paths
B. Current flows in a single path through all components
C. Voltage is the same across all components
D. Resistance is always zero
Answer: B
Rationale: In a series circuit, components are connected
end-to-end, so there is only one path for current.
2. In which direction does current flow?
A. Positive to negative
B. Negative to positive
C. Both directions
D. Neither direction
Answer: B
, Rationale: The source uses electron-flow convention:
electrons flow from negative to positive. Conventional
current is normally described as positive to negative.
3. Current is the ______ throughout the whole circuit.
A. Different
B. Zero
C. Same
D. Maximum
Answer: C
Rationale: In a series circuit, the same current flows
through every component because there is no alternate
path.
4. What are the 4 steps of troubleshooting?
A. Analyze, check setup, calculate/measure, check results
B. Guess, replace, test, repeat
C. Measure, solder, desolder, inspect
D. Analyze, short, open, replace
Answer: A
