Detailed Solution
Download Solution PDFSensitivity of voltmeter:
The sensitivity of the voltmeter is the ratio of the resistance of the instrument (Rm) to the full-scale voltage reading.
The sensitivity (S) of a voltmeter is the reciprocal of full-scale deflection current (Ifsd).
\(S={1\over I_{fsd}}={R_m\over V}\)
The sensitivity of a voltmeter is usually expressed as Ohm/volt.
