A 5V battery with internal resistance `2Omega` and a 2V battery with internal resistance`1Omega` are connected to a `10Omega` resistor as shown in the figure.

The current in the `10Omega` resistor is

A

`0.27A`

B

`0.05A`

C

`0.25A`

D

`0.3A`

Text Solution

Verified by Experts

The correct Answer is:
C
`I_(S)=(2E)/(2r+R)` and `I_(P)=(2E)/(r+2R)`
`r=R`
