Teaching UKPSC Lecturer Mock Test Series 2024 Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
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’.zero inductance. When ‘w’ is increased :
1
the bulb glows brighter
2
the bulb glows dimmer
3
total impedance of the circuit is unchanged
4
total impedance of the circuit increases
