To convert an ammeter into a voltmeter, a high resistance is connected in series with the ammeter. The value of this series resistor is calculated to limit the current to the full-scale deflection value at the desired voltage range.
The full-scale deflection current of a meter is 1 mA and its internal resistance is 100 Ω. This meter is to have full deflection when 100 V is measured. What is the value of series resistor to be used?
