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

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'.

In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.

This primer introduces the student to the correct method of using the internal memory of a TI-86 calculator.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.

In this animated activity, students examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

You have to match the problem with the answer.
