Input voltage depends on ____________(a) resistance(b) capacitance(c) current(d) time-periodThis question was addressed to me in quiz.This question is from Dual Slope Integrating Type DVM topic in portion Electronic Instruments of Electrical Measurements

Answer»

Correct answer is (d) time-period

The best explanation: The INPUT VOLTAGE in a dual slope INTEGRATING type DVM is given by the relation,

Vin = Vref ^t2 ⁄ t1

From the above equation it is seen that the input voltage in a dual slope integrating type DVM depends on the time periods t1 for which the capacitor is charged and t2 during which the capacitor is discharged.
