A heating appliance has a resistance of 115ohm. If 2 A current flows through it , find its power ?

Calculate the current flowing through the following circuit:

When a 12V battery is connected to resistor , 2.5 Ma current flows through the circuit . If so what is the resistance of the resistor ?

The direction of the flow of current through electric circuit is

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.
