Solution - Calculate the Sensitivity of the Moving Coil Galvanometer - HSC Science (Electronics) 12th Board Exam - Physics

Question

A rectangular coil of a moving coil galvanometer contains 50 turns each having area 12 cm2 . It is suspended in radial magnetic field 0.025 Wb/m2 by a fibre of twist constant 15 x10-10 Nm/degree. Calculate the sensitivity of the moving coil galvanometer.

Solution

Given:-

N = 50, A = 12 cm2 = 12 x 10-4 m2,

B = 0.025 Wb/m2,

C = 15 x 10-10 Nm/degree

To find:- Sensitivity (Si)

Formula: Si = NAB/C

Calculation: From formula,

`S_i=(50xx12xx10^-4xx0.025)/(15xx10^-10`

`thereforeS_i=10^6"div/A"`

The sensitivity of a moving coil galvanometer is 106 div/A.
