The measurement of a current is repeated five times. The measured values are:
0.62, 6.21. 6.23, 6.18 and 6.24 mA.
a. What type or types of errors might be involved: mistakes, systematic errors, random errors?
b. Find the best way to estimate the true value.
c. Think of a way of improving the accuracy of the measurement.
d. The experiment is repeated with a more precise current meter, the result is 6.25 ± 0.02 mA. What is the systematic error in the previous measurement?
