Answer :

(a) Least count of the voltmeter is 1.5 / 10 = 0.15 V.

(b) Reading shown by the voltmeter is 1. 5 + 2 (3.0 - 1.5/ 10) = 1.5 + 0.3 = 1.8

(c) Given,

 \sf \: R = 20 \Omega

V = 1. 8

By Ohms law,

V = IR

1. 8 = I ( 20)

1.8 / 20 = I

I = 9/100 = 0.09A

Current flowing through the resistor is 0.09 A
