Answer 1

Answer:

Answer:

The lowest measurable value is known as the least count.

Image:

Voltmeter – System used to calculate the difference in electrical potential between two points in an electric circuit.

we see 10 divisions = 1 volt

So

Least count (LC) = 1/10

LC = 0.1 V

Ammeter – Device used for measuring the current in a circuit.

we see 10 divisions = 0.2 A

LC = 0.2/10

LC = 0.02A
