The scales of an ammeter and a voltmeter are shown below:

Find the least count of the ammeter and the voltmeter.

Explanation

The least count of the ammeter
`= ("Voltage -range")/("Total no. of divisions on its scale")`
`=(6A)/30`
`=0.2A`
The least count of the voltmeter
`=("Voltage -range")/("Total no. of divisions on its scale")`
`=(1.5V)/30`
`=0.05V`
