An electric lamp having coil of negligible indicatanec connected in se

1.	An electric lamp having coil of negligible indicatanec connected in series with a capacitor and an ac source is glowing with certain brightness. If the capacitance is reduced then :–(a) Brightness will remain same(b) Brightness will increase(c) Brightness will decrease(d) Current will increase
Answer» Correct Option (c) Brightness will decrease Explanation: When capacitance C is reduced, X_c(= 1/ωc) increases. This reduces the current and hence brightness of the bulb.

Answer»

Correct Option (c) Brightness will decrease

Explanation:

When capacitance C is reduced, X_c(= 1/ωc) increases. This reduces the current and hence brightness of the bulb.
