Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
Hydraulic Directional Control Valves
By Terry Bartelt
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
Total Power Calculations in a Series Circuit
In this learning activity you'll review the various ways to calculate the total power consumed in a series circuit.
Air Conditioning Machine Operation
By Bill Heesaker
In this lesson the learner will become aquainted with the use of 2 types of A/C machines. They will learn basic operation of the machines controls.
Standard Transmission Signals
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. 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.
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.
Transformer Action Demonstration
Learners view animations and video clips showing how power is transmitted from one energized coil to another.
