Research the specification sheet for bright blue light emitting diode (LED). Find the nominal forward voltage (Vf) and forward current (If) from the sheet. Next, connect the LED to 12 volt DC power supply and a resistor in series. You must determine the resistance of the resistor to limit the current to the value found in the specification sheet. Explain what you found and how you calculate the resistance for this circuit

In this procedure, you get to write and execute an experimental procedure to find a Thévenin equivalent model for a Light Emitting Diode (LED) The simplest model for a diode is as a switch that is on (short circuit) when current tries to flow in the direction of the arrow in the diode symbol, and off (open circuit) when the current ties to flow in the direction opposite to the arrow. This model doesn't work all that well for an...
