A galvanometer of 90 ohms internal resistance has a full-scale current of 350. microA. Describe how to use this meter to make : (a) a 150 V voltmeter, and (b) a 10.0A ammeter
So (a) Resistors must be connected in series with the galvanometer, R=4.29 x 10^5 ohms.
(b) A shunt resistor must be used in parallel with the galvanometer.
