Question

there are 20 divisions between OV and IV on the scale of a voltmeter the least count of the voltmeter is

Answer 1

1/20 = 0.05V
hope this helps

Answer 2

The least count of voltmeter is 0.05 V.

Explanation:

Given that, there are 20 divisions between 0 volt and 1 volt on the scale of a voltmeter. We know that the least count is given by :

$LC=\dfrac{\text{range}}{\text{no of divisions}}$

Here, range is 1 volt and total no of division is 20.

So, the least count of the voltmeter is :

$LC=\dfrac{1}{20}\\\\LC=0.05\ V$

Hence, the least count of voltmeter is 0.05 V.
