EE2791 Measurements Laboratory

University of New Brunswick

Dr. Richard Tervo, P.Eng
< tervo@unb.ca >

Course Description
Laboratory experiments which emphasize basic measurement concepts, techniques and errors, and their analysis through the measurement of current, voltage, resistance, frequency, electric and magnetic field strengths.

Why Study Measurements?

An introduction. Accuracy vs Precision. A trip to the hardware store.

Units in Electrical Engineering

What is a Volt, an Ohm, an Ampere? And who decides how they are defined?

Propagation of Errors

Part 1. In which a measurement is used as part of a computation.

Resistors in the Real World

Why you cannot find a 210 ohm resistor in your parts box.

Propagation of Errors

Part 2. In which probable errors resemble a throw of the dice. The case of series resistors.

Fitting Data to a Straight Line

What your calculator is doing when you try 'linear regression'.

Balancing the Bridge

Where indirect measurements yield accurate results.

The Shocking Truth About RMS Voltage

Why it is not always "one over root two".

Propagation of Errors

Part 3. In which the rules do not seem to work. The case of parallel resistors.
