An ammeter and a voltmeter are connected in series to a battery with an emf ε = 6.0 V. When a certain resistance is connected in parallel with the voltmeter, the reading of the voltmeter decrease η = 2.0 times, whereas the reading of the ammeter increase the same number of times. Find the voltmeter reading after the connection of the resistance.
Text Solution
Verified by ExpertsThe correct answer is:
A
+ η x = ε
⇒ x = 
Reading of voltmeter after connection of resistance is 
= 
= 
= 2V
