What happens when a forward voltage is applied to the rectifier?

What happens when a customer consults the rectifier to add a forward voltage? The following is a brief introduction:

When the rectifier tube (also known as the rectifier diode) is forward-biased, it means that the anode (positive) is applying a positive voltage relative to the cathode (negative).

In this case, the rectifier tube will conduct, allowing current to flow from the anode to the cathode. When the forward voltage exceeds a certain threshold (called the "forward conduction voltage"), the PN junction in the rectifier tube will begin to conduct electricity, reducing the voltage drop at both ends of the tube. In this way, the rectifier tube will act as a low-impedance path, allowing the current to flow. When the rectifier tube is on, its power consumption will depend on the current flowing through the tube and the voltage drop between the anode and cathode.

It should be noted that if the forward voltage applied is too high, the rectifier tube may be damaged by exceeding its rated power. Therefore, when using the rectifier tube, it must be ensured that it does not exceed its forward voltage and current rating.
