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

In this interactive object, learners examine the PN sections of a diode and the diode's forward- and reverse-biased operations. A brief quiz completes the activity.

This learning object introduces the three approximations of a diode.

The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.

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

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