Question

Calculate the work done in moving a charge of 4 coulomb from a point of 220 volts to another point of 230 volts.

Answer 1

Potential difference=230-220

=10V

we know,

Potential difference=work done / charge moved

10=w/4

w=(10×4)V

=40V

Answer 2

$\huge\bold{Answer:-}$

Given :

• Quantity of Charge Moved = 4C

• Potential difference from one point to other point is 220V to 230 V

To Find :- The work Done

Solution:-

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

Charge moved = 4 C

we know ,

Potential difference = $\dfrac{Work \:Done}{Charge \:Moved}$

V = $\dfrac{W}{Q}$

10 = $\dfrac{W}{4}$

W = 10 × 4 j

W = 40 j

Therefore , Work done is 40 joule.
