A bridge rectifier utilizes how many diodes?

A bridge rectifier utilizes four diodes connected in a specific configuration to convert alternating current (AC) to direct current (DC). The arrangement allows current to flow through the load in the same direction during both halves of the AC cycle.

In this configuration, two diodes conduct during the positive half-cycle and the other two conduct during the negative half-cycle, ensuring that the output polarity remains constant. This setup effectively doubles the output voltage compared to a half-wave rectifier while providing better performance overall.

Thus, the correct number of diodes used in a bridge rectifier is four, enabling efficient and reliable conversion of AC to DC.
