Application +4 | -1

A coil has resistance

30\,\,\Omega

and inductive reactance

20\,\,\Omega

at 50 Hz frequency. If an AC source, of 200 Volt, 100 Hz, is connected across the coil, the current in the coil will be

View answer and explanation

Correct option: C

0.166666667

Option A (

\frac{{20}}{{\sqrt {13} }}

) is correct because the current is calculated using the impedance at 100 Hz.
