One micro-ammeter has a resistance of 100Ω and a full scale range of 50 μA. ft 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 combinations (s).
(A) 5 mA range with 1Ω resistance in parallel
(B) 10mA range with 1Ω resistance in parallel
(C) 10V range with 200kΩ resistance in series
(D) 50V range with 10kΩ resistance in series
