The ammeter-voltmeter method is used to measure the of an aircraft instrument resistance. With the voltmeter connected across the resistance, the readings on the ammeter and voltmeter are 0.6 A and 3 V respectively. The resistance of the voltmeter is 500 W. Calculate (i)the true value of resistance and (ii) percentage error in the value of resistance, if the voltmeter current is ignored.
