This article describes how to measure MOSFET drain voltage and current. As part of that discussion it outlines how to use several types of current probes, how to identify the correct measurement ...

Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens and only in AC circuits containing pure resistances. Most AC circuits ...

AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and where each is used.
