Week 6: Series - Parallel Circuits and Potentiometers

You must select one of the Research topics below, or a new topic could be assigned by your Professor. Students will post their research result and will include a PowerPoint presentation and share the research research with the class.

Research/Discussion Topic 1
Research the specification sheet for the 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

Research/Discussion Topic 2
Research how potentiometers work in a circuit and where it is commonly used
