The learner will understand how a zener diode maintains a constant voltage as the resistance values of a load change.
Active Region Operation of a Transistor
By Terry Bartelt
Learners view the operation of an NPN transistor in the active region.
Kirchhoff's Current Law
By Tim Tewalt, Patrick Hoppe
Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
Weight-Volume Relationships: Saturated Unit Weight
By Steve Whitmoyer
Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.
In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. 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.
Instantaneous Voltage Calculations of a Discharging RC Circuit (Using a TI-30XIIS Calculator)
In this animated object, learners view the keystrokes on a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a discharging RC circuit.
Voltages Across Series and Parallel Capacitive Circuits
In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.
Testing a Diode
By Linda Reinke
In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
