Whether circuit may be AC. or D. C. one, following is most effective in reducing the magnitude of the current?
Correct answer: D. Resistor
- A. Reactor
- B. Capacitor
- C. Inductor
- D. Resistor
Explanation
A resistor limits current in both AC and DC circuits because its opposition, R, is present for either type of supply. An inductor does not oppose steady DC, while a capacitor’s opposition depends on AC frequency and it blocks steady DC.
