Upgrade your electronics knowledge! 🚀

In this post, learn about the basic diode (MIC) and the diode bridge (also called a bridge rectifier).

The simple diode lets current flow in one direction, acting as a one-way valve for electricity.

The bridge rectifier uses four diodes to convert AC (alternating current) to DC (direct current), powering your gadgets with steady voltage.
