\(120\,\Omega \) અવરોધવાળા ગેલ્વેનોમીટર સાથે \(1\,\Omega \) નો શંટ અવરોધ જોડેલો છે. \(5.5\, ampere\) પ્રવાહ માટે ગેલ્વેનોમીટર પૂર્ણ આવર્તન દર્શાવે છે. જો શંટ અવરોધ જોડેલો ન હોય તો ગેલ્વેનોમીટર પૂર્ણ આવર્તન વખતે કેટલા .............. \(A\) નો પ્રવાહ દર્શાવશે?

A \(5.5\)
B \(0.5\)
C \(0.004\)
D \(0.045\)

Verified Solution

Answer & Solution

Correct Answer

(D) \(0.045\)

Step-by-step Solution

Detailed explanation

The current that will given full scale deflection in the absence of the shunt is nearly equal to the current through the galvanometer when shunt is connected i.e. \(I_g\) \( \text { As } I_{8} =\frac{1 S}{G+S} \) \(=\frac{5.5 \times 1}{120+1}=0.045 \text { ampere } \)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
