Question

A bulb and a capacitor are connected in series to a source of alternating current. If its frequency is increased, while keeping the voltage of the source constant, then bulb will(a) give more intense light(b) give less intense light(c) give light of same intensity before(d) stop radiating light

Answer 1

Hola User

d} stop radiating light

Thanks

Answer 2

Answer:

A) Give more intense light

Explanation:

Bulb and capacitor are connected in series

Frequency = f = increasing

Voltage = v = constant

Thus,

When a bulb and a capacitor will be connected in a series to an ac source, then when the frequency will be increased the current in the circuit will also increased. this will be because the impedance of the circuit is decreased. So the bulb will give more intense light. Therefore, If the frequency is increased, while keeping the voltage of the source constant, then bulb will give more intense light(
