Question
The resistance of a galvameter is 50Ω and current required to give full scale deflection is 100μF in order to converter it into an ammeter for reading upto 10A. it is necessary to put an resistance of
Options
A.3.5 × 10-4 Ω
B.10 × 10-4 Ω
C.2.5 × 10-4 Ω
D.5 × 10-4 Ω
Solution
G = 50Ω, IG = 100μA, I = 10A
Shunt, S =
G
⇒ S =
× 50
=
× 50 = 5 × 10-4
Shunt, S =
G⇒ S =
× 50=
