This is the 28th in a series of 50+ Hands on Labs. The previous lab dealt with resistance, voltage, current and watts in a series circuit and this lab moves into parallel circuits.

This is the 27th in a series of 50+ Hands on Labs. With this lab we introduce voltage to the circuits and require students to calculate not only Resistance but Voltage, Current, and Power. The concept of "What do I know about this circuit?" (Given), "What can I calculate?" (Calculate), "How else can I gather information?" ( Measure ), and finally, "What does the Theory tell me about the circuit?" (Theory ). The table asks them to simply put the words in each box as to how they will solve for

This is the 26th in a series of 50+ Hands on Labs. This Lab looks similar to the previous lab but is quite advanced and will be a challenge for most. This lab requires students to understand advanced math skills regarding Bridge Circuits. You can not solve this problem the same way as the previous ones. I have included it as a vision to the kind of problems that students will get at the college level. During my time as a Teacher I always found this lab as one of my favorites. It opened the

This is the 25th in a series of 50+ Hands on Labs. This is similar to the previous lab but with the intention of forcing the student to learn advanced troubleshooting skills. The table leads students to think about what is going on in the different parts of the circuit and what to expect by measuring at different parts of the same circuit. This skill is valuable when troubleshooting problems in working equipment. An Electrician who can fix things is worth more than one who only builds.

This is the 24th in a series of 50+ Hands on Labs. This is a very complicated Lab and will test the students understanding of Series and Parallel Circuits. It is very important that they show all their work to verify their understanding of the concepts.

This lab builds on the previous lab by introducing the first Series Circuit Lab. Introducing two resistors in series and how to calculate and measure circuit parameters like Total Resistance in a Series Circuit. Rt = R1 + R2. Answers should be Base units and not in powers of 10. My experience has been that using scientific notation at this point is confusing to the beginning student and not necessary yet. Teaching students to show all their work is very important at this point and keeping e
