8. An ac voltmeter with a maximum scale reading of 50-v has a resistance of 500Ω and an inductance of 0.09 henry. The magnetic coil is wound with 50 turns of copper wire and the remainder of the circuit is a non-inductive resistance in series with it. What additional apparatus is needed to make this instrument read correctly on both d. c. circuits or frequency 60?
