Q4
The current flowing in a resistor is measured 5 times and the results are
recorded as: 1.77 2.21 1.87 2.03 1.92 mA.
The resistor is measured K times; the mean value of these measurements
is 4 n and the standard deviation of the K measured values is 0.4 n.
Stating any assumptions made, calculate an estimate for the voltage in
the resistor and the uncertainty in this measurement; hence write it as
you would present it in a lab report (including units).
