A current of 1 A flows through a coil, when a 100 V d.c. is applied to it. But a current of 0.5 A flows through the same coil, when a 100V a.c. of frequency 50 Hz is applied. The resistance and inductance of the coil are given by (take `pi^(2)=10`)

B. `50 Omega, sqrt0.3 H`
C. `100 Omega, sqrt0.2 H`
D. `100 Omega, sqrt0.3 H`

Answer

D
