Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
The Differentiator Op Amp
By Terry Bartelt
In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.
Feedback System Application
In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
The L/R Time Constant
By Patrick Hoppe
Learners read an explanation of the L/R time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero.
The Digital Logic Probe
Students view the layout and operation of a digital logic probe.
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 Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
An Impedance Matching Application
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
The Reflected Load in a Transformer
Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
