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.
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
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.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.
Learners view a vector diagram for a series RC circuit and read information concerning the voltage across each component, the total voltage, and the phase angle.
Students read an introduction to capacitive reactance and view examples.
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
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 an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
