Two moving coil galvanomenters M1 and M2 having same spring constants and have the following specifications. for galvanomter M1, R1=10 Ω,N1=30, A1=3.6×10−3 m2,B1=0.25 T, for galvanomter M2,R2=14 Ω,N2=42, A2=1.8×10−3 m2,B2=0.5 T Find the ratio of current sensitivity of galavnomter M1 to galvanomter M2

Answer»

Two moving coil galvanomenters M1 and M2 having same spring constants and have the following specifications.

for galvanomter M1,
R1=10 Ω,N1=30,
A1=3.6×10−3 m2,B1=0.25 T,
for galvanomter M2,R2=14 Ω,N2=42,
A2=1.8×10−3 m2,B2=0.5 T

Find the ratio of current sensitivity of galavnomter M1 to galvanomter M2
