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.
