A micrometre has a resistance of 100 Ω and a full scale range of 50µA. It can be used as a voltmeter or a higher range ammeter

Question 1

A micrometre has a resistance of 100 Ω and a full scale range of 50µA. It can be used as a voltmeter or a higher range ammeter provided a resistance is added to it. Pick the correct range and resistance combination (*)

(A) 50V range with 10kΩ resistance in series.

(B) 10V range with 200kΩ resistance in series.

(C) 5mA range with 1Ω resistance in parallel

(D) 10mA range with 1kΩ resistance in parallel.

Question 2

Correct option (B, C)

Explanation:

Let range of voltage be V

Let resistance added be R

so cannot be ammeter
