What is the difference between a rectifier bridge and a rectifier diode?

What are the differences between rectifier bridges and rectifier diode? At the same power, the rectifier bridge is more compact and occupies less space than the bridge composed of rectifier diode, and the consistency between each rectifier diode of the rectifier bridge is definitely better than that between individual rectifier diodes.

However, there are still drawbacks. The price of the rectifier bridge is generally higher than the sum of four individual rectifier diode, and some parts are damaged and cannot be repaired. Compare between the following two, then:

1. Is it better to use a diode or a rectifier bridge for rectification? Both can be used, and the effect is the same. Using a rectifier bridge is simpler;

2. Whether to use transformers or resistors for voltage transformation: Of course, transformers are better, as using resistors consumes a lot of power and is not safe;

3. Is it better to filter parallel capacitors or series inductors? It is best to use both, that is, π type filtering. However, if the requirements are not high, parallel capacitors are sufficient.
