The most important electronics terms, demystified in one place.


Our Take

The anode is the p-doped side of a diode, typically considered where the current flows *in*. When looking at the symbol, the anode is the "back" of the arrow, on the opposite side of the vertical line.

When solving circuits with diodes in them, you always assume that the anode is the positive side of the diode. Zener diodes are the only exception to this.
