Two resistances of 400 
and 
are connected in series with 6 volt battery of negligible internal resistance. A voltmeter of resistance 
is used to measure the potential difference across 400 
. The error in the measurement of potential difference in volts approximately is
Text Solution
Verified by ExpertsThe correct answer is:
D
Before connecting voltmeter potential difference across 
resistance is
After connecting voltmeter equivalent resistance between A and 
Hence, potential difference measured by voltmeter
Error in measurement
