Question

calculate the electric potential difference to do 40 j of work on 36 c of charge
​

Answer 1

Answer:

Explanation:

Given :-

Work done = 10 joule

Charge =  2 Coulomb

Potential of point A = V(a) = 10 J/2 C = 5 V

Given :-

Work Done = 20 Joule

Charge = 2 coulomb

Potential of Point B = V(b) = 20 J/2 C = 10 V

Solution :-

Potential Difference between Point A and B = V(a) -  V(b)

⇒ Potential Difference between Point A and B = 10 V - 5 V

⇒ Potential Difference between Point A and B = 5 V

Now, Work done directly from A to B,

Work Done = Potential Difference × Charge

⇒ Work Done = 5 V × 2 C

⇒ Work Done = 10 Joule

Hence, the potential difference between two points A and B is 5 V and the work done if the same charge is brought directly from A to B is 10 Joule.
