ETron Circuit LabsLab 6Intro to PotentiometersObjective:In this Lab, you will learn that a Potentiometer is a variable resistor. You may also see it referred to as a Rheostat.Step 1 – Take InventoryUsing the Parts Inventory as shown on the right under the “Here’s What You’ll Need” section, place each part needed for this experiment on its corresponding drawing. Observe the schematic symbol for each part. Make sure that you have all the parts ready before you begin Step 2.Step 2 – Build the CircuitUsing the Schematic Diagram and the picture of the completed lab, build the lab experiment with the electronic components. Use the “Check Your Work Here” Box to verify that your wiring is correct, and then proceed to Step 3Step 3 – Do ExperimentTheory:In this electronic circuit consisting of an LED, a 220 Ohm resistor (to keep the LEDs from burning out fromtoo much current when the Potentiometer is adjusted to zero Ohms), a 9-volt battery, and a Potentiometer, the electrons flow from the battery through the resistor, through the LED, through the Potentiometer, and back to the battery.
