In this interactive object, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information. A brief quiz completes the activity.

In this learning activity you'll review the various ways to calculate the total power consumed in a series circuit.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.

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

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.

This review covers magnetism, static electricity and electrical safety from Unit 6!

You will answer questions over physics, chemistry, space, biodiversity, and physical and chemical change. Compete against your other classmates in this board game have fun and don't cheat.
