Question : If the current through a galvanometer is I=kθ/NAB, then what is the sensitivity of the galvanometer?
a)NAB/k
b)k/NAB
c)NAB/kθ
d) None of the above.
Doubt by Tanya
Solution :
We know
Current sensitivity (IS) = θ/I
I=kθ/NAB
NAB/k=θ/I
θ/I=NAB/k
Current Sensitivity (IS) = NAB/k
Hence, a)NAB/k is correct.
