Is there a device or method for automatically (non manually) varying a resistor?
Basically we have A thermoelectric with an internal resistance, hooked up to a load resistor, and we want peak power (which is when the load resistance matches the internal resistance). Right now we are manually (rheostat) changing the load resistance by turning a knob, but would like to have a method that automatically matches the load resistance with the internal resistance.
Any ideas?
