Question

What is the work done in moving 0.5 C charge across two points having potential difference of 8 V ?

• A. 4

Answer 1

The correct option is A 4
The potential difference ($V$) between two points is the amount of work done ($W$) in moving a unit positive electric charge ($q$) from one point to another in a current carrying conductor.

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

Given: $q=0.5C$
$V=8V$
Therefore, the work done in moving the charge $=8V\times 0.5C=4J$.
