In the experiment of calibration of a voltmeter,a 1.1 V standard cell gets balanced at length of wire.The balancing length correspondind to a potential difference between the ends of a resistance comes out to be 190 cm.a voltmeter shows 0.5 V for this potential difference.The error in the reading of the voltmeter will be

a.0.025 V

b.25 V

c.2.5 V

d.0.25 v

Dear Nenka ,

The error of the voltmeter is 0.25 V.

Best Of Luck...!!!!
