Two scales on a nondigital voltmeter measure voltages up
Chapter , Problem 91(choose chapter or problem)
Two scales on a nondigital voltmeter measure voltages up to 20.0 and 30.0 V, respectively. The resistance connected in series with the galvanometer is 1680 V for the 20.0-V scale and 2930 V for the 30.0-V * * ** * scale. Determine the coil resistance and the full-scale current of the galvanometer that is used in the voltmeter.
