An inductor-coil , a capacitor and an AC source of rms voltage `24 V` are connected in series. When the frequency of the source is varied, a maximum rms current of `6.0 A` is observed. If this inductor coil is connected to a battery of `emf 12 V` and internal resistance `4.0 Omega`, what will be the current?

Text Solution

Verified by Experts

The correct Answer is:
`1.5 A`
`R=24/6=4 Omega , I=12/4+4=1.5` Amp.
