Transistor Fundamentals: JFET Amplifiers
Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.
Transistor Fundamentals: JFET Drain Curves
Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.
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.
Transistor Fundamentals: Review of Logarithms
Students review logarithms as they pertain to electronics.
Transistor Fundamentals: The MOSFET
Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.
Voltage Divider Rule (VDR)
Students review the Voltage Divider Rule and work practice problems.
Voltage Divider Rule Practice Problems
Learners review the VDR and work six problems. Immediate feedback is given.
Voltage Drops
In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.
Voltage Source Approximations
Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.
What Is Current?
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.
