Question

Multimeter can be used for D.C. voltage measurement by ________

(a) connecting series resistances

(b) connecting shunt resistances

(c) connecting star delta resistances

(d) using a switch

I have been asked this question in a job interview.

This intriguing question comes from Electronic Multimeter topic in section Electronic Instruments of Electrical Measurements

Answer 1

Correct choice is (a) connecting series resistances

To explain: We can obtain a wide range of D.C. voltage from a multimeter by connecting various series resistances in the circuit through a range selection switch. By adjusting the value of the resistance we get the required D.C. voltage.
