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.
