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.

Students read how to use the IMCONJUGATE() function to convert complex numbers to their conjugate in rectangular form.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.

Students examine the four factors that affect resistance of a wire: temperature, length, diameter, and the type of material from which it is made. A short quiz completes the activity.

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

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

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

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
