What is constant current power?

Constant current can also be called steady flow, meaning similar, generally can be no difference.

Compared with the concept of constant voltage, the concept of constant current is difficult to understand, because constant voltage sources are common in daily life, batteries and dry batteries are DC constant voltage power supplies, while 220V AC power can be considered as an exchange. Constant voltage power supplies, because their output voltage is basically constant, does not vary greatly with the magnitude of the output current.

First give an example:

A constant current source with a constant current value of 1A and a maximum output voltage of 100V. When you turn on the power switch of this constant current source, what values do you see on the voltmeter and ammeter of the power supply? It can be said with certainty that the output voltage is 100V and the output current is 0A. Someone once asked, are you not a constant current source of 100V 1A? How is the output not 100V 1A? It is still necessary to explain this by Ohm's law. In theory, the output voltage of the power supply is U=IR, where U is the output voltage, I is the output current, and R is the load resistance. Constant current can also be called steady flow, meaning similar, generally can be no difference.
