Question

In a DVM, a transducer converts ________

(a) input to a proportional current

(b) input to a proportional power

(c) input to a proportional voltage

(d) input to a proportional resistance

I got this question in my homework.

I need to ask this question from Digital Voltmeters in chapter Electronic Instruments of Electrical Measurements

Answer 1

Correct choice is (c) input to a proportional voltage

To elaborate: In a digital voltmeter, a transducer is used. In general a transducer converts a physical quantity into an electrical signal. In a DVM the transducer converts the input signal into a proportional voltage.
