Question

(a) Calculate the work done in moving a charge of 4 coulombs from a point at 220 volts to another point
230 volts.
that helps to measure the potential difference across a conductor.
​

Answer 1

Answer:

$\fbox{\underline{\Huge{\texttt{40 J}}}}$

Explanation:

Here we have

Q(charge) = 4 Coulomb

V(Potential Difference) = 230V - 220V = 10V

We want work done so by using

W = VQ

W = 4 $\times$ 10

W = 40 J
