Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.

In this interactive object, learners answer nine questions about inductors.

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

In this animated object, learners examine the operation of a temperature alarm circuit that uses a thermistor in a Wheatstone Bridge.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

In this learning activity you'll practice converting between hexadecimal and decimal and between hexadecimal and binary numbers.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.

Let's test ourselves on what we have learnt from the website, shoot the correct answers as quick as you can!
