Chapter 19, Problem 54P

To determine

The current in the galvanometer for full-scale deflection.

Answer to Problem 54P

The current in the galvanometer for full-scale deflection is $5\times {10}^{-7}\text{A}$ .

Explanation of Solution

Given info:

The sensitivity of the ammeter is, $s=20000\text{Ω}/\text{V}$ .

Formula Used:

The expression to calculate the current in the galvanometer for full-scale deflection is,

  $I=\frac{1}{s}$

Calculation:

Substitute all the values in the above expression.

  $\begin{array}{c}I=\frac{1}{20000\text{Ω}/\text{V}}\\ =5\times {10}^{-7}\text{A}\end{array}$

Conclusion:

Thus, the current in the galvanometer for full-scale deflection is $5\times {10}^{-7}\text{A}$ .
