Students review the Voltage Divider Rule and work practice problems.
Horizontal Curve Components
By Steve Whitmoyer
Learners view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.
An Impedance Matching Application
By Terry Bartelt
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
The TI-83 Plus Calculator: Using the LOG Function
By Patrick Hoppe
Students follow the correct keystrokes to calculate the logarithm of a number.
Learners observe animations showing how data is converted between serial and parallel flow.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
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.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
