Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
The Induction Motor Slip
By Terry Bartelt
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
Inductive Reactance Demonstration 1
Learners view video clips showing how coiled wire provides more resistance to AC current flow than uncoiled wire.
Parallel RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Hydraulic Directional Control Valves
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
Measuring Length in the Metric System
By Nabila Dahche
In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.
How to Convert from One Unit to Another in the Metric System
In this learning activity you'll practice converting from one metric unit to another.
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.
Oscilloscope Frequency Measurements
Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
