NEET (UG) 2024 — Question 11

The terminal voltage of the battery, whose emf is 10 V and internal resistance $1 \Omega$ , when connected through an external resistance of $4 \Omega$ as shown in the figure is:

Option A:
4 V
Option B:
6 V
Option C:
8 V
Correct
Option D:
10 V

Answer: C

Step-by-step solution

Current in circuit $i=\frac{10}{4+1}=2 \mathrm{~A}$

Terminal voltage $=E-i R$

=10-2 \times 1=8 \mathrm{~V}
