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.
