Explanation:
A microammeter has a resistance of 100W and a full scale range of 50 µA. 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(s). <br> (1) 10V range with 200 kW resistance in series. <br> (2) 50V range with 10 kW resistance in series. <br> (3) 5 mA range with 1W resistance in parallel. <br> (4) 10 mA range with 1 kW resistance in parallel
