Question

Electronic voltmeters are __________

(a) dependent of frequency

(b) dependent of voltage

(c) independent of frequency

(d) dependent of current

The question was posed to me by my school teacher while I was bunking the class.

The above asked question is from Advantages of Electronic Instruments topic in division Electronic Instruments of Electrical Measurements

Answer 1

Right choice is (c) independent of frequency

For explanation: Usually electronic voltmeters can measure frequency in the range of a few volts D.C. to frequencies of the order of hundreds of MHz. As a result, the effect of frequency on the response of electronic voltmeters is negligible.
