The approach to dc circuit analysis is presented to the learner. The approach is demonstrated for the student.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students view the equations used to determine the ac parameters of the transistor circuit.

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.

In this learning activity you'll practice converting from one metric unit to another.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.
