least count of ammeter is 0.1 A and voltmeter is 0.1V
sundypilathara:
can you tell how you got the answer
there is a formula in 11th to find least count chapter is unit and dimensions
but how bro pls tell

Answer:
LC of ammeter = 0.2 / 10
= > 0.02 A
A = 0.02 A
LC of Voltmeter = 1 / 10
= > 0.1 V
V = 0.1 V
Current = 15 x 0.02 A = 0.3 A
Potential difference = 21 x 0.1 V = 2.1 V
