Solution

Step 1- Given data
Charge $Q = 1000 C$
Potential difference $V = 12 V$
The formula for work done $W$ is
$W = Q V$
Step 2- Finding the work done in moving the charge
Substitute the values of the potential difference and charge,
$W = (1000 C) \times (12 V) W = 12, 000 J$
Final answer- The work done in moving a charge of $1000 C$ across two points having a potential difference of $12 V$ is $12, 000 J$ .
