1 Volt is the potential difference between two points in a current carrying conductor when one Joule work is done to move a charge of 1Coulomb from one point to the other. / $1V = \frac{1J}{1C}$
$V = \frac{W}{Q}$
$W=QxV$
$W = 1.6 \times 10^{-19} \times 100$
$W = 1.6 \times 10^{-17} J$
$V = \frac{W}{Q}$
$W=QxV$
$W = 1.6 \times 10^{-19} \times 100$
$W = 1.6 \times 10^{-17} J$
