Question

when a shunt
a shunt of 40 ohm is connected
with a galvanometer then the deflection on remain 1/5 . If 20ohm shunt resistance is also connected with this Combination then how much will be
deflection remain?​

Answer 1

Answer:

Explanation:

When only 4Ω resistance is shunted (i  

g

​  

)  

1

​  

=i/5

G×1/5=4×(4/5)=16Ω

(i  

g

​  

)  

2

​  

=  

16+(4/3)

4/3

​  

i=
