Current Electricity Charging Discharging Of Capacitors Question 279
Question: 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
[EAMCET 2000; KCET 2002]
Options:
A) Both A and V will increase
B) Both A and V will decrease
C) A will decrease and V will increase
D) A will increase and V will decrease
Show Answer
Answer:
Correct Answer: D
Solution:
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.
