Problem 20. The current I flowing in a resistor R is measured by a 0-10A ammeter which gives an indi- cation of 6.25 A. The voltage V across the resistor is measured by a 0-50V voltmeter, which gives an indication of 36.5 V. Determine the resistance of the resistor, and its accuracy of measurement if both instru- ments have a limit of error of 2% of f.s.d. Neglect any loading effects of the instruments.

You’re working on a new high-speed rail system. It uses 6000-horsepower electric locomotives, getting power from a sin-gle overhead wire with resistance 15 mΩ/km, at 25 kV potential relative to the track. Current returns through the track, whose resistance is negligible. Energy-efficiency standards call for no more than 3% power loss in the wire. How far from the power plant can the train go and still meet this standard?
