To convert a moving coil galvanometer to a voltmeter, we add a high series resistance, but why?. The high resistance causes most of the voltage to drop across it, leaving a small voltage drop across the galvanometer. This also ends up making the voltmeter have very high resistance. Ideal voltmeters have infinite resistance.

An alternative is to use a constant current source of I current with a variable current sink that adjusts to from 0 to 2*I. That allows an output current of +/- I. WebElectrical – Bipolar Voltage to Current Converter. I need a circuit or component which converts bipolar voltage to bipolar current. I have found the XTR111 from Texas Instruments and the 1B22 from Analog Devices. However, they only convert 0-10 V to 0-20 mA current. I to need convert -10V-0V to -10mA-0mA too (the opposite polarity range).
