Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

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

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.

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.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.
