how much work is done in moving a charge of 4 coulomb across two points having potential difference of 12volt ?calculate the no.of electrons flowing in it

Open in App

Solution

Dear student

We know
W= QV
where V is the potential difference
Q is the charge
W is the work done
So,
W = 4 x 12
W = 48J
