Question

Q1. The voltage across a resistor is measured 5 times and the results are recorded as: Voltage measurements (Volts) 9.21 8.76 9.01 9.53 9.41 The current passing through the same resistor is also measured 5 times and the values are recorded as Current measurements (milliamps) 43.1 44.7 39.9 41.6 42.7

Showing all your calculations and assumptions, calculate an estimate for the energy dissipated in the resistor in 20 seconds and for the uncertainty in this energy value; hence write it as you would present it in a lab report.
