JEE Main · 2024 · 08 Apr 2024 · Shift 1 · Current Electricity

In the given circuit, the terminal potential difference of the cell is :

(A)2 V✓ Correct
(B)4 V
(C)1.5 V
(D)3 V

Answer: (A)

Solution

The two

4 Ω

resistors are in parallel:

\frac{4 \times 4}{4 + 4} = 2 Ω

. With the cell (

E = 3 V

,

r = 1 Ω

),

i = \frac{E}{r + R} = \frac{3}{1 + 2} = 1 A

Terminal p.d.

V = E - i r = 3 - (1) (1) = 2 V

. Option (A).
