In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Students read an introduction to capacitive reactance and view examples.
Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
