Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

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 alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.

Formulas and Functions in Microsoft Excel

A learning object to illustrate the right way to enter formulas and functions in Excel.

In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.

In this learning activity you'll explore the operation of frequency division using several different types of counters.

This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.
