15 EET 20 30 Lab2
In this lab you are to demonstrate your ability to calculate what will occur with respect to a
simple parallel circuit, perform a theoretical calculation and do physical measurements.
These sets of labs will confirm our theoretical statements we have made as well as demonstrate
that you have the ability to test and measure on live circuits.
For this lab you will need:
Breadboard
Power supply
3 resistors all with the same resistance
Calculations:
Complete the following chart.
