Which Side Of A Diode Is Positive?

In a diode, the side that is typically considered positive is called the anode, while the side that is considered negative is called the cathode. The anode is typically marked with a "+" symbol or a longer lead, while the cathode is marked with a "-" symbol or a shorter lead.

It's important to note that the positive and negative designations of a diode depend on the context in which it is being used. In forward bias mode, where the diode allows current to flow, the anode is positive with respect to the cathode. In reverse bias mode, where the diode blocks current, the anode is negative with respect to the cathode.
