A coil draws a current of `1.0` ampere and a power of `100` watt from an `A.C.` source of `110` volts and `(5sqrt22)/pi` hertz. Find the inductance and resistance of the coil.

Text Solution

Verified by Experts

The correct Answer is:
`sqrt(21/22)H-100 Omega`
`I_(rms)^(2)xxR=100` --(1)
`(1)^(2)xxR=100 rArrR=100 Omega`
`V_(rms)=I_(rms)Z , 110=I_(rms)Z , 110=1xxZ=sqrt(R^(2)+(omegaL)^(2)) , L=sqrt(21/22)H`
