One of the safest ways to measure current is with a clamp. Clamps do not require you to break the circuit and they safely measure wires with thousands of amps. In this video, we measure DC current in the lab, AC current of a reflow oven controller, and the DC current in a car using a Tenma 72-7226 True RMS Clamp Meter. This video was the last one I did before moving to a new…

Starting with this new AddOhms TutorialCast series, we are taking a look at Electronics Basics.  The first topic is on the differences between Voltage, Current, and Power. The twist on this explanation is that we are not using the usual “electricity is like water” analogy engineers seem to love.  Instead, we just use plain language to explain the difference between these concepts.
