Additional Details

Conceptual Physics Alive: Electric Current includes a digital video and questions set with answers.

Concepts in electric current and examples of Ohm's law are discussed. Series and parallel circuits are demonstrated using a car battery that has extended terminals. Segment length: 30 minutes

Electric Current Includes:

  • Begins by reviewing the Van de Graaff generator and the surrounding electric field.
  • Voltage defined.
  • Energy transferred by the generator compared to the energy transferred by a common household circuit.
  • Analogy to heat and temperature.
  • Current and voltage difference.
  • Water flow analogy of electric current.
  • Demonstration of single lamp attached to car battery.
  • Hewitt discusses childhood experiences with electricity.
  • Birds on high-tension wires.
  • Boston MTA story.
  • Cherry picker story.
  • 2nd Boston MTA story.
  • Ohm's law defined.
  • Water flow analogy.
  • DC and AC defined.
  • Washing machine analogy.
  • Amount of electrons that flow in an AC circuit (none}.
  • Demonstration of a series circuit with a battery, and many questions.
  • Demonstration of a parallel circuit with a battery, and many questions.

Next-Time Question: As more and more resistors are connected to a parallel circuit, does the overall resistance of the circuit become more, less, or stay the same? (SEE RESOURCES TAB FOR MORE)
