7. In order to determine the power dissipated across a resistor, the current flow and resistance values are measured separately. If I = 3.2 A and R = 10000. Instrument Uncertainty (% of reading) Voltmeter 0.5% Ohmmeter 0.1% Ammeter 0.5% . Power can be measured as P = l²R or P = VI. Which method will give the most accurate measurement?
