A galvanometer of resistance50 Ωis converted into an ammeter by connecting a low resistance (shunt) of value1 Ωin parallel to the galvanometer,S. If full-scale deflection current of the galvanometer is10 mA, then the maximum current that can be measured by the ammeter is -

Options:

Answer:
B
Solution:

S=GIgI–Ig

Shunt and Galvnometer are in parallel combination



1=50×10I–10

I-10=500

I=510 mA
