In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.

Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.

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.
