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, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.

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

Students read about decibel power gain and decibel voltage gain. Examples are given for each.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

Learners read how to set up a TI-86 calculator. The process is demonstrated and examples are given.

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.
