Given that Charge,q = 1 C Potential difference V = 6 v To find out We need to find the energy given to each coulomb of charge passing through a 6 V battery. Principle of conservation of energy Formula Potential difference (V)= Work done (W) / Charge (q) On rearranging the above formula, we get Work done (W) = Potential difference X Charge Put the value of V and q in the above equation, we get Work done (w) = 6 X 1 Work done = 6 Joules Therefore, the energy is given to each coulomb of charge passing through a 6 v battery is 6 J.
