Learners read a description of the DC offset function, the 50 ohm and 600 ohm output terminals, and the TTL/CMOS output terminal.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

In this animated and interactive object, learners follow two methods for converting a hexadecimal number to a decimal number. They test their knowledge in exercises at the end of the learning object.

In this interactive object, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
