ANSWER
Calibration of Voltmeter
Observations measured from voltmeter is errorful due to different reasons:
(i) In built mechanical error,
(ii) Parallex error,
(iii) Unsymmetrically in the spring of voltmeter etc.
Potentiometer can increase precise value of potential difference.
Checking the errors of observations of voltmeter by potentiometer is known as Calibration of Voltmeter.
In figure. necessary circuit diagram is shown for calibration of voltmeter. Primary circuit is usually connected as section before.
In secondary circuit positive terminal of standard cell is connected at point A (high potential end) while negative terminal is connected with the terminal 1 of two way key. In this circuit other cell ϵ, rheostate Rh
