Question

A shunt of resistance is 1ohm connected across a galvanometer of resistance 120 ohm. A current of 5.5 ampere gives full scale deflection in the galvanometer. The current that will give full scale deflection in absence of shunt is nearly​

Answer 1

Answer:

0.045

Explanation:

The current  will give full scale deflection in the absence of shunt is nearly equal to the current through galvanometer when shunt is connected.

Ig = I × S / G+S

Ig = 5.5×1/120+1

Ig = 0.045
