If the switch at point P is opened (which was initially closed), choose the correct option (s).

A

The current in `R_1` would not change.

B

The potential difference between point X and the ground would increase.

C

The current provided by the battery would decrease.

D

The emf produced by the battery (assumed to have no internal resistance) would change.

Text Solution

Verified by Experts

The correct Answer is:
B, C
b., c.
Let a current I flows in circuit, then
`V_(G) + E - IR_1 = V_(X) - V_(G) = E-IR_1`
It switch is opened, then equivalent resistance increases so I
decreases. Hence `V_(X) = V_(G)` increases.
