Calculate the coil resistance

Reference no: EM13294867

Two scales on a voltmeter measure voltages up to 20.0 V and 28.0 V, respectively. The resistance connected in series with the galvanometer is 1680 ? for the 20.0-V scale and 2930 ? for the 28.0-V scale.

(a) Determine the coil resistance?

(b) Determine the full-scale current of the galvanometer that is used in the voltmeter.
