Question #52418
When a direct current of 2 A is passed through a coil, the potential difference across the coil
is 20 V. When an alternating current of 2 A at frequency 40 Hz is passed through a coil, the
potential difference across the coil is 140 V. Find the current in the coil if it is connected to
a 230 V, 50 Hz supply.
