QNEET-2022-Ph-529: NEET 2022 Physics - Class 12 NEET-2022-Ph-529 Solution: A cell of emf 4 V and internal resistance \(0.5 \) is connected …
A cell of emf 4 V and internal resistance is connected to a external resistance. The terminal potential difference of the cell is 0.375 V 3.75 V 4.25 V 4 V
Multiple Choice Options
- A 0.375 V
- B 3.75 V
- C 4.25 V
- D 4 V
Step-by-Step Verified Solution
From Kirchhoff's loop law :
V _ I r _ I R = 0
_ I = ( V r + R )
Terminal potential difference across cell,
V A B = I R
V A B = R V r + R
= 7.5 _ 4 0.5 + 7.5 = 3.75 V
