About this part
Troubleshooting Electronic Circuits with a Digital Multimeter
(#1201-LAB)
A complete hands-on troubleshooting lab designed to teach students how to measure, analyze, and interpret electronic circuits using a professional digital multimeter.
Why This Lab Stands Out
The Mr Circuit Labs go beyond simply “assemble the circuit and make it work.” Students use real electronic components — the same parts used by engineers and technicians in the field.
Each lab includes a professional solderless circuit board (breadboard) and teaches students to apply math, science, and problem-solving skills to real troubleshooting situations.
Because Mr Circuit Labs are reusable, schools can provide authentic electronics technology training for only a few dollars per student.
What Students Learn
- Use Ohm’s Law and Watt’s Law in real circuits
- Calculate equivalent resistance (series & parallel)
- Measure voltage, current, and resistance with a digital multimeter
- Interpret multimeter readings correctly
- Analyze voltage drops and LED behavior
- Design and troubleshoot practical LED circuits
What’s Included
- Digital Multimeter
- Solderless circuit board (breadboard)
- 9-Volt battery power source
- 10 colored 5mm LEDs
- 14 resistors for testing and measurement
- Printed lessons and fully illustrated instructions
- Online video lessons and quizzes
- Printable Certificate of Electronics Training
Classroom Ready
All experiments are powered by a 9-volt battery — no extra power supplies or tools required.
Lessons can be projected onto a Smart Board for guided instruction or completed independently. Make-up lessons are simple using the included video presentations.
Ideal for STEM, STEAM, Automotive, HVAC, Robotics, Avionics, and Electronics programs.
