The learner will understand how a zener diode maintains a constant voltage as the resistance values of a load change.
The Neutral Current of an Edison Wire System
By Terry Bartelt
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
Parallel Circuit Analysis Practice Problems Part 1
By Patrick Hoppe
In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.
Ohm's Law Practice Problems #2
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.
Powers of Ten: The Proper Use of Symbols
Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.
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.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
Kirchhoff's Voltage Law with Complex Numbers
Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
