Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.

Learners review Ohm's Law and then 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.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

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.

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

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

The questions include tides, waves, currents, and coastal erosion.

You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.

Students will review facts about ocean currents.
