JEE Mains · Physics · STD 12 - 3. current electricity

આપેલ પરિપથમાં \(1\; \Omega\) અવરોધમાથી પસર થતો પ્રવાહ \(I_{1}\) (\(A\) માં) કેટલો હશે?

  1. A \(0.5\)
  2. B \(0.2\)
  3. C \(0.25\)
  4. D \(0.4\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(0.2\)

Step-by-step Solution

Detailed explanation

Equivalent resistance of upper branch of circuit \(\mathrm{R}=2.5 \Omega\) Voltage across upper branch \(=1 \mathrm{V}\) \(\Rightarrow \quad i=\frac{1}{2.5}=.4 \mathrm{A}\) \(\Rightarrow \mathrm{I}_{1}=0.2 \mathrm{A}\)
