In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.

Answer questions about biology in a game of baseball

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.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.

Understand the op-amp buffer configuration and calculate basic circuit impedance.

The learner will understand the circuit configuration and operation of an integrator op amp.
