An ac source of variable angular frequency and constant amplitude is connected in series with a capacitance C and an electric bulb of resistance R. When angular frequency is increased then: |
total impedance of the circuit increases total impedance of the circuit is constant the bulb glow brighter the bulb glow dimmer |
the bulb glow brighter |
The correct answer is Option (3) → the bulb glow brighter |
