Two Circuit Questions

  1. Aug 10, 2007 #1
    1. An electrical meter has an internal resistance of 5k Oh, and registers full scale of 50 microA. How many mega Ohm to insert in series to turn meter into a 1000 range voltmeter?

    2. An electrical supply line loading question. Some large piece of electrical equipment ahs a peak power output of 2000 kW. If this is maintained, but voltage changed from 480V to 240V, by what ratio will supply line losses change

    Thank you.

    Why isn't this posted in the Homework section? Does anybody ever read the rules?
