Two scales on a voltmeter?
Two scales on a voltmeter, which is constructed from a galvanometer, measure voltages up to 24 V and 32 V respectively. The resistance connected in series with the galvanometer is 1655 for the 24 scale and 2594 for the 32 scale.
Find the full-scale current of the galvanometer. (The full-scale current is the same in both scales.)
