one of my client asked me " What is the main different between "Constant Voltage and Constant Current"
If you know about that, Could you mind to tell me in english, thanks a lot !
for your reference

Constant voltage: the power supply works as a voltage-source. when the load impedance changes, the output voltage keep constant.
And constant current, the power supply works as a current-source, when the load impedance changes, the output current keep constant
