A current of 0.5 A is drawn by a filament of an electric bulb for 10minutes. Find the amount of electric charge that flows through the circuit

How much work is done in moving a charge of 2 C across two points having a potential difference 12 V

The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. What current will the heater draw if the potential difference is increased to 120 V?

A 4 Ω resistance wire is doubled on it. Calculate the new resistance of the wire.

100 J of heat are produced each second in a 4 Ω resistance. Find the potential difference across the resistor.
