Answer 1

Answer:

hey mate here is ur ans

Explanation:

let r1= 1ohm

r2 = 20ohm

r3 = 4ohm

v1 = 14 volt

v2 is volmeter which we have to find it

r1 and r2 are in the series

R' = r1+r2 = 1+20 = 21 ohm

let I is current passing through a v1

I = v/R' = 14/21 A

consider only a new circuit

v2 = I ×r3 = 14/21×4 = 56/21 volt

hope it help u
