Solution

The correct option is A 60 J
Work done by a battery = potential difference $\times$ total charge passed
$⟹ W o r k d o n e = 12 V \times 5 C$
$W o r k d o n e = 60 J$

The correct option is A 60 JWork done by a battery = potential difference × total charge passed⟹Workdone=12V×5CWorkdone=60J

The correct option is A 60 J
Work done by a battery = potential difference $\times$ total charge passed
$⟹ W o r k d o n e = 12 V \times 5 C$
