The potential difference between the two end terminals of an electric heater is 220 V and the current through it is 0.5 A. What would be the current through the heater if the potential difference across the terminals of the heater is reduced to 120 V?

If potential difference and current flowing through a wire is increased twice each then electric power :

A light bulb rated as 60 W at 220 V has a potential difference of 110 V across its ends. The power dissipated in this light bulb is :

The work done in moving a charge of 2 coulomb (C) from point A to point B is 24 J. What is the potential difference between A and B?

An electric bulb is connected to a 110 V generator. The current is 0.2 A. What is the power of the bulb?

An electric bulb is rated as 220 V and 80 W. When it is operated on 10 V, the power rating would be :
