A microammeter has as resistance of `100 Omega` and full scale range of `50 muA`. It can be used a voltmeter or as ahigher range ammeter provided a resistance is added to it. Pick the correct range and resistance combinations
50 V range with `10 kOmega` resistance in series
b.`10 V` range with `200 kOmega` resistance in series
c. 5mA rangw with `1Omega` resistance in parallel
`10 mA` range with `1Omega` resistance in parallel
A. 50 V range with 10 `kOmega` resistance in series
B. 10 V range with 200 `kOmega` resistance in series
C. 10 mA range with `1Omega` resistance in parallel
D. None of the above
