Discussion Forum : Alternating Current
Question -
A bulb and a capacitor are in series with an ac source. On increasing frequency how will glow of the bulb change
Answer: Option B
:
B
The glow increases because, when frequency vis increased, the capacitive reactance Xc=12πvCdecreases and hence the current through the bulb increases which will lead to increase in glow
