A rectangular coil having 100 turns each of length 1.0 cm and breadth 0.5 cm is suspended in radial magnetic field of induction 0.02 T the torisional constant of suspension fibre is `2xx10^(-8)` Nm / degreee calculate current sensitivity of MCG

Options

A. 500 div /A
B. 600div /A
C. 400 div / A
D. none of these

Explanation

To calculate the current sensitivity of the moving coil galvanometer (MCG), we will follow these steps:

### Step 1: Understand the formula for current sensitivity
The current sensitivity (S) of a moving coil galvanometer is given by the formula:
\[ S = \frac{\theta}{I} = \frac{N \cdot B \cdot A}{C} \]
where:
- \( \theta \) = angular deflection (in degrees)
- \( I \) = current (in Amperes)
