[NEET Odisha 2019]

(a) $0.4 V$

(b) $0.6 V$

(c) $0 V$

(d) $0.5 V$

Show Answer

Answer:

Correct Answer: 96. (a)

Solution:

  1. (a) Current in first branch $=\frac{2}{50} A$

Current in second branch $=\frac{2}{50} A$

$\Delta V$ from $A$ to $P$

$\Delta V_1=2-\frac{2}{50} \times 20$

$\Delta V$ from $A$ to $Q$

$\Delta V_2=2-\frac{2}{50} \times 30$

$\Rightarrow$ Voltage difference $=0.4 V$
