An ammeter and a voltmeter of resistance R are connected in series to an electric cell of negligible internal resistance. Their readings are A and V respectively. If another resistance R is connected in parallel with the voltmeter
Text Solution
Verified by ExpertsThe correct answer is:
D
After connecting a resistance R in parallel with voltmeter its effective resistance decreases. Hence, less voltage appears across it i.e., V will decreases. Since overall resistance decreases so more current will flow i.e., A will increase.
