A microammeter has a resistance of 100 Ω and a 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(s).
- 50 V range with 10 kW resistance in series
- 10 V range with 200 kW resistance in series
- 5 mA range with 1 W resistance in parallel
- 10 mA range with 1 W resistance in parallel.
Answer
(B) 10 V range with 200 k W resistance in series
