In circuit shown below, the resistance are given in ohms and the battery is assumed ideal with emf equal to 3 volt The voltage across the resistance `R_(4)` is

A

0.4 V

B

0.6 V

C

1.2 V

D

1.5 V

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(eq) = 50 + 50/2 = 75 Omega`
`I = 3/75 =1/25 A`
`I_(4) = (60/(60 + 30)) xx 1/(2 xx 25) = 6/9 xx 1/50 =1/75 A`
`V_(4) = 1/75 xx 30 = 10/25` Vol = 0.4 Volt
