Physics · Alternating Current
An AC voltage source of variable angular frequency 'ω' and fixed amplitude 'V0' is connected in series with a capacitance C and an electric bulb of resistance 'R' (having zero inductance). When 'ω' is increased:
- 1the bulb glows brighter✓
- 2the bulb glows dimmer
- 3the total impedance of the circuit remains unchanged
- 4the total impedance of the circuit increases
Correct answer
the bulb glows brighter
