Silly Job Title: Wattage Warlock. I am the Wattage Warlock!

In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and measure our DVM’s current output in diode test mode.

We use the Fluke 17B+ Digital Multimeter for voltage and current measurements.

We use the EEVblog BM2257 Digital Multimeter for voltage and current measurements.

We use the Carpenter Mechanical Pencil to take notes.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
