The learner will understand how a zener diode maintains a constant voltage as the resistance values of a load change.
Voltage Source Approximations
By Patrick Hoppe
Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.
The Ideal Bode Plot
The Ideal Bode plot is introduced. The three main topics covered are: corner frequencies, midband voltage gain, and the roll-off rate.
Gear Ratio Concepts (Screencast)
By James Bourassa
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
The learner will identify components of a welding robot and determine if the robot is set up correctly to avoid singularity.
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
By Terry Bartelt
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.
