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.
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.
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.
From all the work that we have done so far, you should be able to introduce and explain to others what the greenhouse effect is. Play this short and fun game to test your knowledge.
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.
