How much work is done in moving a charge of $2$ coulomb from a point at $118$ volt to a point at $128$ volt ?
How much work is done in moving a charge of $2$ coulomb from a point at $118$ volt to a point at $128$ volt ?
Given $\quad q=2 C , V _{1}=118 V$
and $\quad V _{2}=128 V , W =?$
We know that $V =\frac{ W }{q},$ therefore,
$W=q\left(V_{2}-V_{1}\right)=2(128-118)=20 J$
