Three batteries of emf 1V and internal resistance 1 `Omega` each are connected as shown. Effective emf of combination between the points PQ is –

A

Zero

B

1 V

C

2 V

D

`(2)/(3) V`

Text Solution

Verified by Experts

The correct Answer is:
A

`E_("net")=(E_(1)r_(2)-E_(2)r_(1))/(r_(1)+r_(2)) =(2-2)/(2+1)=0`
