Click to download and view Preview Copy of Training Manual  for this lab.

Educational Tutorial Lab for:

S.T.E.M. --- Automotive --- HVAC --- Avionics --- Electronics --- Robotics etc.

With this lab, you will work with formulas for Ohm's Law, Watts Law, calculate the equivalent resistance of resistors in series and parallel, use a multimeter to determine the ohms of resistors in series and parallel, calculate resistor wattage, calculate resistor values in LED circuits, calculate and measure current in series and parallel circuits, calculate and measure voltage drops, and more.

You will get practice reading resistor values, current, and voltage on the display of the Digital Multimeter. You will also get more practice using a solderless circuit board to build electronic circuits. (See the whole Skill Set below.).

This lab was created to meet the needs of  S.T.E.M. --- S.T.E.A.M. --- Automotive --- HVAC --- Avionics --- Electronics --- Robotics etc.

I have trained many technical people and one of their biggest needs was to know how to use and interpret the readings on a multimeter.  This knowledge and experience will open up more opportunities at employment and entrepreneurship.

Each lab comes with a password protected link to view or print out a copy of the pdf file of a 76-page, 30-lesson hands-on lab manual.

All components necessary for the experiments are included. No extra tools are needed. The lab includes a 9 volt battery power source, a solderless circuit board to build circuits, 10 colored 5mm LEDs (red, green, yellow, blue, clear) and 14 resistors for testing and measuring and a multifunction Digital Multimeter.
