In the circuit shown, the internal resistances of the batteries are indicated next to them. Choose the correct option(s):

A

(A) The potential at P is -7.5

B

The potential at Q is -1V

C

The potential at R is zero

D

The potential at S is zero

Text Solution

Verified by Experts

The current in the circuit `I=((20-10))/((7.5+0.5+1+1))=10/10-1amp`
The potential difference across PS, `V_(ps)=7.5 times 1=7.5V`
The potential difference across Q,R, `V_(QR)=1 times 1=1V`
As point G is connected to earth, hence potentials of R and S are zero.
The direction of the current in the circuit is from P to S, hence point P is at higher potential
`therefore V_p=7.5V`
Similarly, `V_Q=-V therefore` Hence (B) ( C) and (D) are correct
