Share:
- 1The capacitor charges and discharges fully within each half-cycle.
- 2The voltage across the capacitor forms a triangular waveform of small amplitude because it cannot charge or discharge fully during a half-cycle.✓
- 3The voltage across the capacitor becomes a series of sharp spikes.
- 4The capacitor acts as a short circuit to the DC component of the pulse.
Correct answer
The voltage across the capacitor forms a triangular waveform of small amplitude because it cannot charge or discharge fully during a half-cycle.
