πππ‘πππ‘πππ π·πππππππππ=ππππ ππππ/πΆβππππ
or Work done (or Energy) = Potential Difference Γ Charge
So, Work done = 6 Volt Γ 1 Coulomb = 6 Joules

Energy given by battery = charge x potential difference
or W = QV = 1C X 6V = 6J.
Given, Charge Q = 1C, Potential difference, V = 6V
Therefore, Energy i.e. Work done, W =?
We know that, V =Β W/Q
Therefore, 6V =Β W/1C
βΒ W = 6V Γ 1C = 6J
Thus, required energy = 6J
The amount of energy given to each coulomb of charge passing through a battery can be determined using the formula:
Energy (in joules) = Voltage (in volts) Γ Charge (in coulombs)
In this case, you mentioned a 6 V battery. So, if 1 coulomb of charge passes through this battery, the energy provided would be:
Energy = 6 volts Γ 1 coulomb
Therefore, the energy given to 1 coulomb of charge passing through a 6 V battery is 6 joules.
