Detailed Solution
Download Solution PDFThe correct answer is option 4):(1 kΩ/V)
Concept:
Concept:
Sensitivity of voltmeter is commonly expressed in ohms per volt Sensitivity of voltmeter is the ratio of resistance of the instrument (Rm) to full scale reading of the same.
Sensitivity (S) of a voltmeter is the reciprocal of full-scale deflection current (Ifsd)
Total internal resistance of a voltmeter is given by
Rm =
Rm = full scale range of voltmeter × sensitivity
Rm = Vfsd × S
Calculation:
Given, Ifsd = 1 mA
Sensitivity (S) =
= 1000 Ω/V
= 1 kΩ/V
