📘Question

A galvanometer having a coil of resistance 30 Ω need 20 mA of current for full-scale deflection. If a maximum current of 3 A is to be measured using this galvanometer, the resistance of the shunt to be added to the galvanometer should be 30/ X Ω, where X is

(1) 447 

(2) 298 

(3) 149 

(4) 596                                                      (JEE-2025)
