Question

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

Answer 1

Step 1: Given Data

From the question, it is given that $V=6V$ and $q=1C$.

Step 2: List the known values and formula

The potential difference between two points is defined as the amount of work done required to bring a unit positive charge from one point to the other point.

If $V$ is the potential difference, $W$ is the work done and $q$ is the charge, then

$V=\frac{W}{q}$

$\therefore W=Vq$

Step 3: Calculate the energy

$\therefore W=6\times 1$

$=6J$

Hence, $6J$ energy is given to each coulomb of charge.
