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

5. A light emitting diode (LED) is a diode that lights up when a current flows across it. The symbol for an LED is shown below (sometimes wiggly arrows are used to represent the light instead.) For this question we will assume we are working with LEDs that have a turn-on voltage of VoN-1V and a reverse breakdown voltage of VBR-8V a. You hook up a single LED to a power supply that can put out vol tage from -10...

Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
