Build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and inspect them using lab instruments such as voltmeters and ammeters.

Sample Learning Goals

  • Discuss basic electricity relationships.
  • Build circuits from schematic drawings.
  • Use an ammeter and voltmeter to take readings in circuits.
  • Provide reasoning to explain the measurements and relationships in circuits.
  • Discuss basic electricity relationships in series and parallel circuits.
  • Provide reasoning to explain the measurements in circuits.
  • Determine the resistance of common objects in the "Grab Bag."
  • Discuss how a capacitor in a circuit charges up and then discharges.
  • Discuss the behavior of an inductor in a circuit.
