Learners read an analogy comparing an electrical transformer to mechanical gears.

In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

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.

In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.

The student reads about encoding, storage, and retrieval and test his or her memory in an interactive exercise.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll review the operation of a NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this learning activity you'll describe the operation of a logic inverter using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
