Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
In this animated and interactive object, learners study how a DC circuit, consisting of a diac, a capacitor, and two resistors, causes a light-emitting diode to turn on and off. A brief quiz completes the activity.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
Charging Time Constants of an RC Circuit (Screencast)
In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.
