Question

The resistance of a 20 mV voltmeter is 1000ohm. How can u convert voltmeter to ammeter which can measure upto 2 A. Draw the necessary circuit diagram

Answer 1

Answer:

Converting an ammeter to a voltmeter involves increasing the resistance of the ammeter. This is done by adding a high resistance in series with the ammeter. Let the range of the ammeter be 0 – I0 Amp and we convert it to a voltmeter of range 0 – V0 volt.
