When 200 volts dc is applied across a coil a current of 2A flows through it. When 200 V ac of 50 Hz is applied to the same coil only 1A flows. Calculate the resistance impedance and inductance of the coil.

When 100 V DC source is connected across a coil a current of 1A flows through it. When 100 V, 50 Hz AC source is applied across the same coil only 0.5 A flows. Calculate the resistance and inductance of the coil.

When 100 V DC source is connected across a coil a current of 1 A flows through it. When 100V, 50 Hz AC source is applied across the same coil only 0.5 A flows. Calculate the resistance and inductance of the coil.

On an iron box is marked as 690 W, 230 V. What is the current flowing through the coil ?

An electric bulb is labelled 40W, 200V. Calculate the current flowing through it?

A coil draws a current of 1A and a power of 100W from an ac source of 110 V and 50 Hz. Find the resistance and the inductance of the coil?
