Answer 2

The least count of the milliammeter is 5mA.

Given:

In a milliammeter, there are 20 divisions between the 400ma mark and 500ma.

To Find:

The least count of milliammeter.

Solution:

The least count of an instrument is the smallest and most accurate value in the measured quantity that can be resolved on the instrument's scale.

Least Count = Range of the instrument / No of division

= 500 - 400 / 20

= 100/20

= 5

Therefore, the least count of the milliammeter is 5mA.
