In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

Learners answer 14 questions about series-parallel DC circuits.

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.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

In this learning activity you'll explore the operation of frequency division using several different types of counters.

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

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.

Converting hexadecimal, binary and decimal numbers.
