# How much energy is given to each coulomb

Question.
How much energy is given to each coulomb of charge passing through a 6 V battery ?

solution:
Work done, $\mathrm{W}=\mathrm{QV}$ where $\mathrm{Q}=1 \mathrm{C} ; \mathrm{V}=6 \mathrm{~V}$

$\mathrm{W}=1 \mathrm{C} \times 6 \mathrm{~V}=\mathbf{6} \mathbf{J}$
