In the circuit shown, battery, ammeter , and voltmeter are ideal and the switch S is initially closed as shown. When switch S is opened

A

equivalent resistance across the battery increases

B

power dissipated by left resistance R increases

C

voltmeter reading decreases

D

ammeter reading decreases.

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
a., c., d.
When switch S is opened, parallel connection across battery
decrease. Hence, equivalent resistance across the battery
increases, power dissipated by left resistance R decreases,
voltmeter reading decreases and ammeter reading decreases.
