I have a question:
Do I understand correctly that the amperage draw of a device is determined by the internal resistance and " current needs" of the device??
Therefore, if I use a 15vdc 1.5a power supply or a 15vdc 5a power supply, it does not matter, because the device will determine the actual amperage taken from the power supply ?
Thus, if the device actually needs/uses 1a, both of these supplies would work without harming the device? Or does excess amperage available put the device into danger of over-current?
The only way that the amperage to the device would increase is by increasing output voltage or lowering the internal resistance in the device?
