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.

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.

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 animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

Parallel Circuit Analysis Practice Problems Part 1

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

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.
