2.3 A DC voltmeter (scale set to 20 V) is used to measure the voltages across a resistor (470 resistor with a 10% tolerance). The voltmeter displays a true voltage of 12 V when measuring the input to the resistor, and a voltage of 9 V when measuring its output to ground. The voltmeter has an accuracy of approximately 5%. 2 ASSIGNMENT 2 FOR 2022 - METROLOGY III 2.3.1 Calculate the average power (in dBm) dissipated in the resistor.
