Mr Circuit Multimeter Fundamentals Lab 1201-P

With this lab, your students will learn electronics technology, and they will have a way of proving that they have. No longer will prospective employers or customers just have to take their word for it.  Upon completion of this lab, you will print out and give them an official signed  8 1/2 x 11" Certificate of Electronics Training that can be added to their resume.  They can display it with pride in their room or office. 

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.

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, as we said,  a multifunction Digital Multimeter.

This lab can be used for individual instruction as well as a lock-step classroom program.  

For students who miss an instruction period, make-up is very easy. The student can watch the video lesson presentation, study the written lesson, and do the experiment.

This lab is also a perfect activity when you have a Substitute Teacher. 

 There are online video lessons included.
