Question:

The value of a resistor R is to be determined using the ammeter€“voltmeter setup shown in Figure P28.63. The ammeter has a resistance of 0.500 Ω, and the voltmeter has a resistance of 20 000 Ω. Within what range of actual values of R will the measured values be correct to within 5.00% if the measurement is made using the circuit shown in
(a) Figure P28.63a and
(b) Figure P28.63b
