NEET · Physics · STD 12 - 3. current electricity

જો પરિપથમાં ગેલ્વેનોમીટર \(G\) કોઈ આવર્તન દર્શાવતુ ન હોય તો \(R\)નું મૂલ્ય \(..........\,\Omega\) થાય.

  1. A \(400\)
  2. B \(200\)
  3. C \(50\)
  4. D \(100\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(100\)

Step-by-step Solution

Detailed explanation

Since galvanometer does not show any deflection \(\Rightarrow i_g=0\) \(\frac{10-2}{400}=\frac{2}{R} \Rightarrow R=\frac{2 \times 400}{8}=100\,\Omega\)
