How do constant current constant voltage devices work?
The potentiometers adjust the maximum current and voltage that the supply will deliver. With no load, the supply will produce the maximum voltage that you set. As you increase the current, the voltage will remain steady until the load reaches the maximum current setting, then the voltage will reduce to keep the current constant.
How does increasing voltage or current affect the power?
Assuming your load is a resistor and you do not change the original value of your resistor (i.e. 2.5Ω), then you would have to increase the voltage of the circuit to 20V to increase current in the circuit to 8A (20V/2.5Ω). ... and thus the current will change exponentially with the voltage. In summary, if you specify the relationship between ...
