A moving coil galvanometer has 150 equal divisions. Its current sensitivity is 10 divisions per milliampere and voltage sensitivity is 2 divisions per millivolt. In order that each division reads 1 volt, the resistance in ohms needed to be connected in series with the coil will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Voltage sensitivity 
⇒ ⇒ 
.
Here 
Full scale deflection current 
.
V = Voltage to be measured = 150 × × 1 = 150 V.
Hence 
.
