In this interactive object, learners use the Law of Cosines to calculate forces.
Effects of a Rheostat in a Series Circuit
By Terry Bartelt
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
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.
The TI-83 Plus Calculator: Using the Arctangent Function
By Patrick Hoppe
Learners read how to use the arctangent function to calculate the theta of an angle. The proper keystrokes are displayed.
How Metal Detectors Operate
Learners examine how metal detectors function. This object includes animation and sound.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Kirchhoff's Voltage Law
Students read a definition of Kirchhoff's Voltage Law and view examples of its use.
Reading a Micrometer
By Sue Silverstein
In this learning activity you'll practice reading a micrometer.
Kirchhoff's Voltage Law (KVL): Practice Problems
By Terry Fleischman, Patrick Hoppe
Learners review Kirchhoff's Voltage Law and work six practice problems. Feedback is given.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
