Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.

This passage will test your knowledge on capacitors.

College-level physics course highlighting electricity and magnetism. This course is divided into several modules including electric fields, magnetic fields, electromagnetic forces, conductors and dielectrics, electromagnetic waves, and...

In this activity, students' will use a voltage probe to collect voltage data from a discharging capacitor. They will model potential data using an exponential function.

Learners investigate electrostatics with conductors. Some topics explored in the activities are electric shielding, conductors, and charging by induction. The resource consists of video clips, lecture notes, online textbook chapters,...

AC circuits with capacitors and inductors respond to the frequency, as well as the voltage. Find the frequency value that reduces the circuit power to half the maximum.
