Question

A micro-ammeter has a resistance of 100 Ohm anf full scale range of 50micro Ampere. It can be used as a voltmeter and an ammeter of a higher range provided a resistance is added to it. Pick the correct range and resistance combination(s) :-

(A) 50 V range and 10 kilo Ohm resistance in series

(B) 10 V range and 200 kilo Ohm resistance in series

(C) 5 mili ampere with 1 ohm resistance in parallel

(D) 10 mili ampere range with 1 Ohm in parallel

Answer 1

It can be used as a voltmeter and an ammeter of a higher ... Pick the correct range and resistance combination(s)
