Question

Q . A micro ammeter has a resistance of 100Ω and full scale range of 50 µA. It can be used as a voltmeter or as a higher range ammeter provided a resistance is added to it. Pick the correct range and resistance combination :- (1) 50 V range with 10kΩ resistance in series (2) 5 mA range with 1Ω resistance in parallel (3) 10 mA range with 1Ω resistance in parallel (4) none of these
