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.
Effects of a Rheostat in a Series-Parallel Circuit
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
Transistor Fundamentals: Junction Field Effect Transistor (JFET)
Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.
The learner will study an effective workplace email being written while a narrator explains the step-by-step process. The learner will distinguish the difference between poorly written and effectively written emails.
Public Speaking for Biosecurity Advocates II: Presenting Effectively
Be the force to create a safer agricultural community by creating and presenting effective educational presentations. By informing others about biosecurity strategies, you’ll become a biosecurity advocate as you spread the word about its importance!
Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.
The Effect of Temperature on the Vapor Pressure of a Liquid
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
Learners follow the FMEA process to predict potential failures and to prevent them. This activity uses the example of getting to work to help participants comprehend the concepts and to apply them to their own work processes.
Automotive Electrical Systems: Effects of a Rheostat in a Series Circuit
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.
In this learning activity you'll review an introduction and samples of description worksheets. You'll then select an object and complete your own description.
