Learners review the VDR and work six problems. Immediate feedback is given.
Surface Texture Symbols
By Glenn Sokolowski
Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.
Series-Parallel Circuit Analysis Practice Problems: Circuit 2
By Patrick Hoppe
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
By Terry Bartelt
In this animated object, learners examine the operation of an optocoupler, specifically how it is connected to external components to provide interfacing and isolation and how it responds to excessive frequencies. A quiz completes the activity.
Finding the Common Connection of an SPDT Switch
In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.
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.
Using a Lumber Rule
By Patrick Molzahn
Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
How to find the total voltage, when the voltages across R1,R2,R3 is given.
