Question

In the given the internal resistance of the battery is 1.5 ohm and vp and vq are potential at p and q respectively.What is the potential difference between the points p and q

Answer 1

Answer:

- 2.5 v

Explanation:

Given In the given the internal resistance of the battery is 1.5 ohm and vp and vq are potential at p and q respectively.What is the potential difference between the points p and q

We know that

Req = 5/2 ohms

i = 20/5/2 + 1.5

  = 5 A

Potential difference between x and p  

Vx – Vp = 5/2 x 3 = 7.5 v--------1

Vx – Vq = 5/2 x 2 = 5v----------2

Solving 1 and 2 we get

Vp – vq = - 2.5 volt

Vq > Vp
