If a power of 100 W is being supplied across a potential difference of 200 V , current flowing is

A bulb of 100 W is connected across a source of 200 V . Find the current drawn by it .

When a current of 2 A flows in a battery from negative to positive terminal, the potential difference across it is 20 V. If a current of 3 A flowing in the opposite direction produces a potential difference of 25 V, the emf of the battery is

When a current of 2 A flows in a battery from negative to positive terminal, the potential difference across it is 12 V. If a current of 3 A flowing in the opposite direction produces a potential difference of 15 V, the emf of the battery is

Write the relation between electric power (W ) of a device with potential differnece (Volt) across it and current ( amp ) flowing through it.

A car battery with a 12V e.m.f. and an internal resistance of 0.04 Omega is being charged with a current of 50A. The potential difference V across the terminals of the battery are:

An electric bulb, when connected across a power supply of 220V , consumes a power of 60 W . If the supply drops supply is suddently increased to 240 V , what will be the power consumed?
