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

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

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

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.
