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?
12 V
Correct Answer: (c) 12 V
Explanation: Potential difference (V) is given by the formula V = Work Done / Charge. Here, V = 24 J / 2 C = 12 V.
A current of 0.6 A is drawn by an electric bulb for 10 minutes. Which one of the following is the amount of electric charge that flows through the circuit?
A current of 1.0 A is drawn by a filament of an electric bulb for 10 minutes. The amount of electric charge that flows through the circuit is
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?
Two conducting wires of the same material and of equal lengths and equal diameters are first connected in parallel and then in series in a circuit across the same potential difference. The ratio of heat produced in parallel and series combinations 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?
