Ohms Law Trainers

Ohms Law Trainers are paper-sized PCBs (8.5×11″) with real, working circuits for practicing Ohm’s law: one board of 9 series circuits, one board of 8 parallel circuits, increasing in complexity as you work through each. Each trainer board is laid out exactly the same as the problems on a matching paper worksheet.

Every resistor has a test point for multimeter probes, and each circuit includes a switch to break the loop for current measurement.

Includes free downloadable worksheets: one set with practice problems to solve by hand and verify by measuring the real circuit, and a second set where you measure two values, calculate the third, and confirm it on the board.

Free Worksheet Downloads

Here is where you can download the paper worksheets that go along with the Ohms Law Trainer boards. This download button will download a single zip folder with everything you need:

  • Each worksheet in PDF and Inkscape SVG format. PDF is printer friendly, SVG format can be opened in Inkcsape.
  • One worksheet each for series and parallel with some values filled in. You can use this version by itself and mathematically calculate each value, then check your work with a multimeter.
  • One worksheet each for series and parallel with no values. Measure any two values with your multimeter, then calculate the remaining value
  • An answer key for series and parallel.
