Which of the following circuit elements is used to 'block' DC in an electronic circuit ?
Correct answer: B. Capacitance
- A. Resistances
- B. Capacitance
- C. Inductance
- D. Diode
Explanation
A capacitor charges briefly and then blocks steady direct current, while allowing alternating current to pass depending on frequency. A resistor limits current and an inductor tends to oppose changes in current rather than simply block DC.
