Question

calculate the work done in moving a charge of 4 coulombs from a point at 220 volt to another point to 230 volt​

Answer 1

Explanation:

Given

charge (Q)=4C

electric potential at 1st point=220V

electric potential at 2nd point=230V

the charge is moving from 1st to 2nd

Potential difference=10V

W=VQ=10×4=40J

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 = 10V

• 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.
