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 increase.

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
b. If P is disconnected , `R_(eq)` of circuit increases, hence less current
is drawn. Therefore, `0+2iR_1-x`
Therefore, as i decreases, x increases.
