Question:

A circuit you're building needs a voltmeter that goes from \(0 \mathrm{~V}\) to a full-scale reading of \(5.0 \mathrm{~V}\). Unfortunately, the only meter in the storeroom is an ammeter that goes from \(0 \mu \mathrm{A}\) to a full-scale reading of \(500 \mu \mathrm{A}\). It is possible to use this meter to measure voltages by putting it in a measuring circuit as shown in Figure P23.67. What value of \(R\) must you use so that the meter will go to full scale when the potential difference \(\Delta V\) is 5.0 \(\mathrm{V}\) ? Assume that the ammeter is ideal.image text in transcribed
