In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.
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 object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
Buying a Car: What It Really Costs with Finance Charges (Screencast)
In this learning activity you'll calculate the difference in the total cost of a new car when using cash and when paying for the car with a 60-month loan.
Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
