4. An impedance coil is connected in series with a 16 - ohm resistance.
The combination is connected across a 220V, 60 Hz source. If the
voltage across the coil is 150 V while that across the resistance
is 50V, determine the inductance of the coil.
5. An impedance coil, in series with a resistor takes a current of 5
A when connected to a 100 volt AC source. Using a voltmeter, the
voltage across the coil was found to be equal to 80 V and across
to the resistor is equal to 30 V. Find the operating factor of the
