1. The problem statement, all variables and given/known data How would I go about determining the Thevenin equivalent of a simple circuit involving a battery and an LED? I suppose there could be a series resistor to prevent excess draw and burning out of the diode. This question seems very odd since LEDs by definition don't involve a linear relationship between voltage and current. 2. Relevant equations Thevenin's theorem 3. The attempt at a solution Not sure how to go about starting this.
