In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.

Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.

You'll determine which of two options is the correct choice for rounding a given number to the nearest tenth, hundredth, or thousandth.

You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
