Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.
Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.
Students read the vocabulary associated with frequency response as it relates to an amplifier.
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Learners read a description of the DC offset function, the 50 ohm and 600 ohm output terminals, and the TTL/CMOS output terminal.
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Students follow steps to transfer data from a list to a histogram.

In this animated activity, learners read an explanation of the four different modalities (currents) used in electrotherapy.
Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.
Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.
In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.
Learners examine how a radiation pyrometer converts the frequency of electromagnetic waves to a temperature reading.
In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
