For the LCR circuit, shown here, the current is observed to lead the applied voltage. An additional capacitor C', when joined with the capacitor C present in the circuit, makes the power factor of the circuit unity. The capacitor C', must have been connected in : • Option 1)

series with C and has a magnitude • Option 2)

series with C and has a magnitude • Option 3)

parallel with C and has a magnitude • Option 4)

parallel with C and has a magnitude 666 Views

As we learnt in

Power factor -

Ratio of resistance and impedance.
