8. In an experiment of calibration of voltmeter, a
standard cell of emf 1-1 V is balanced against 440
cm or potentiometer wire. The potential difference
across the ends of a resistance is found to balance
against 220 cm of the wire. The corresponding
reading of voltmeter is 0.5 volt. Find the error in the
reading of voltmeter.
[Ans. - 0-05 V]
