Answer 1

Option d

Explanation:

Potential across PM,

Vᴘᴍ = 4 × 1 = 4 V

Now, equivalent resistance across PN

1 / Req = 1 / 0.5 + 1 / 0.5

Req = 0.5 / 2 = 0.25 Ω

Effective resistance between P and M

Rᴘᴍ = 0.25 + 1

Rᴘᴍ = 1.25 Ω

For balancing condition,

Vᴍɴ / Vᴍᴘ = Rᴍɴ / Rᴘᴍ

Vᴍɴ = Vᴘᴍ × Rᴍɴ / Rᴘᴍ

Vᴍɴ = 1 / 1.25 × 4

Vᴍɴ = 3.2 V

∴ The potential difference between the points M and N is 3.2 V !

Answer 2

Answer:

♣️Potential Difference between the point ( M and N) is 3.2V ♣️
