Learners examine the electronic components of a digital thermometer.

Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

Learners follow the seven steps involved in the lockout/tagout procedure. This activity has video content demonstrating the safety measures.

The learner will understand the circuit configuration and operation of an integrator op amp.

In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

This learning object introduces the three approximations of a diode.

In this animated lesson, students view how an oscilloscope and a DC voltmeter measure the voltage of a half-wave rectifier.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
