Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
Transistor DC Analysis Practice Problems: Circuit #2
By Patrick Hoppe
Learners analyze a base-biased npn transistor circuit. A "help" screen is available.
Setup Reduction/Quick Changeover
By Kaye Krueger
Learners view steps to reduce changeover time in a manufacturing operation.
By Terry Bartelt
In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.
Rotating Vector Representation of the Sine Function
The learner will be able to represent steady-state AC sinusoidal signals using phase vectors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
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.
You'll review and learn biology HSA terms.
