Learners review Ohm's Law and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.

In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

Students read how to determine and calculate the degree of saturation for a given sample of soil or aggregate based on the weight-volume relationship.

In this animated object, learners examine the operation of various circuits that are internal to the inductive proximity sensor.

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.
