This learning activity describes the abilities of an inductor coil to oppose alternating current and to pass direct current.
Learners read a description of inductors and view examples of inductors in series and in parallel.
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.
This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.
Learners read an explanation of the L/R time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero.
Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
