Share:
- 1A π-filter (pi filter) generally provides better filtering than a simple LC filter.
- 2In a series inductor filter, ripple factor increases with load resistance, while in a shunt capacitor filter, ripple decreases with an increase in load resistance.
- 3A capacitor opposes changes in current, while an inductor opposes changes in voltage.✓
- 4A filter is used to reduce ripples/fluctuations in the rectifier output.
Correct answer
A capacitor opposes changes in current, while an inductor opposes changes in voltage.
