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 work practice problems to calculate the total resistance of a circuit. Feedback is provided.

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.

Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

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

Learners view animations and video clips showing how power is transmitted from one energized coil to another.
