Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
The TI-86 Calculator: The Square Root Function
By Patrick Hoppe
Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.
Op Amps 5: Non-Inverting Amplifier Circuit Resistance
By Todd Van De Hey
The learner will calculate basic circuit resistance.
By Terry Bartelt
In this animated object, learners examine the ratio control method used in automation when two or more ingredients are mixed. A brief quiz completes the activity.
The Firing Circuit of a DC Drive
In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
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.
