2. A voltmeter is connected directly in parallel with an unknown resistance (R), and an ammeter is directly in series with a de supply connected to the resistance and voltmeter. The ammeter is on 1 mA range and its resistance is 0.1 The voltmeter, which has a sensitivity of 10k/V, is on its 5 V range. The indicated quantities are 500 μA and 4 V. Determine: a) The normal resistance of R b) The maximum and the minimum resistance of R if the voltmeter and the ammeter accuracies are +1%. (10 Marks) 20 ER
