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

Explanation

To solve the problem, we need to analyze each option based on the given microammeter specifications: a resistance of \(100 \, \Omega\) and a full-scale range of \(50 \, \mu A\). We will determine if the combinations of voltage ranges and resistances are valid for converting the microammeter into a voltmeter or a higher range ammeter.

### Step-by-Step Solution:

1. **Understanding the Microammeter**:
- The microammeter has a full-scale reading of \(50 \, \mu A\) and a resistance of \(100 \, \Omega\).
- The maximum voltage it can measure (when used as a voltmeter) can be calculated using Ohm's Law: \(V = I \times R\).
