This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.

In this learning activity you'll calculate the total inductance of a series circuit.

Students work nine practice problems to determine the total inductance of a parallel circuit. Immediate feedback is given.

Students work nine practice problems to determine total series inductance. Immediate feedback is given.

Learners view video clips showing how coiled wire provides more resistance to AC current flow than uncoiled wire.

Learners read a description of inductors and view examples of inductors in series and in parallel.

In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.

Learners read an explanation of the RL 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. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

Learners examine the process for determining the total inductance of a parallel circuit. They then complete practice problems.

Students read an introduction to transformers that includes schematic symbols, turns ratios, mutual inductance, and the coefficient of coupling.
