EGR 224/Measurements

This page will contain some tips and pictures for the EGR 224 Labs on Electrical Measurements.

Tinkercad

Go to www.tinkercad.com to set up your account. Note - for the lab report, you will be uploading four screen shots to show the four different wiring configurations. You do *not* need to take three pictures of each voltage division configuration; just take a picture with one set of resistors in place showing the measurement across the top resistor (A). You will need to write down the other values obtained, however.

Schematics

These are Tinkercad representations of how you should build your physical circuits. Your wiring should generally match these. For your Tinkercad simulations, you can either build the circuit three times or you can move the multimeter wires. You will only be required to turn in a screen capture of the middle circuit, showing how you simulated measuring the resistance across the top resistor.

Lab 2

Voltage Divider - Voltage Measurements

There are three different measurements you need to make. The first will be the total voltage - go by what your multimeter says and not by the digital readout on the powered breadboard. The second will be measuring the voltage drop across the top resistor (A), and the third will be measuring the voltage drop across the bottom resistor (B).

Lab 3

Note in the pictures below that the pink wires do not actually exist - they are internal to the PBB.
