A cell of emf 1.4V and internal resistance `2 Omega` is connected in series with a resistance of `100 Omega` and an ammeter. The resistance of the ammeter is `4/3 Omega`.To measure the potential difference between the two ends of the resistance a voltmeter is connected IF the reading of the voltmeter is 1.10V, what will be its error?

Text Solution

Verified by Experts

Voltmeter should record `V_(CD)=4/3=1.33V`
`therefore` Error in the reading of the voltmeter
=1.33-1.10=0.23 V
