In this section, describe the different circuit designs, show mathematical equations, and simulated
output. When inserting an equation, use the Equation Editor, e.g.: R2

You should also include schematics, and discuss expected results. Experimental Procedure
1. Measure Voltage Differences
Build the simple circuit shown, Vi = 5(V) (DC voltage), then measure the amplitude of the signals
at A and B with respect to ground. Figure 1 2. Voltage Divider
Display the signal generator output, note its amplitude, then connect the1k potentiometer as shown.
Connect the B probe to the sliding output of the potentiometer. Figure 2
3. Investigate a Current Divider
Build the current divider shown below, using RAC = 2k, 10k, 15k respectively.

In the lession, we learned about how to use breadboard and the way to read resistor color codes
and capacitor code. The exercises show us the difference between calculations and reality when
measuring electrical circuits. This is the foundation to know more about the principles of EE.
