Transistor Fundamentals: Classes of Operation
By Patrick Hoppe
Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.
Instantaneous Voltage Calculations of a Charging RC Circuit (Calculator TI-30XIIS)
By Terry Bartelt
Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a charging RC circuit.
Capacitive Reactance
Students read an introduction to capacitive reactance and view examples.
Voltage, Resistance, and Current Relationships
In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.
Characteristics of the TTL Series
Learners read the characteristics of the TTL series. Examples are given and subfamilies are compared.
Crank Slider Velocity
By James Bourassa
In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.
Integral Reset Setting
Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.
DC Compound Motors
Learners study animation showing the operation of cumulative and differential DC compound motors. A short quiz completes the activity.
Automatic PLC Counting
By Terry Bartelt, Tom Yapp
Learners study an animated PLC counting operation and examine how the count is automatically reset.
Maximum Proximity Sensor Switching Speed
In this animated object, learners study what happens if the maximum switching speed of a proximity sensor is exceeded.
Transistor Fundamentals: Review of Logarithms
Students review logarithms as they pertain to electronics.
Mechanical Advantage (Screencast)
By James Bourassa, John Rosz
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
The Reflected Load in a Transformer (Screencast)
Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.
Print Reading: Slotted Block
In this learning activity you'll illustrate your ability to visualize a slotted block.
Quick-Return Mechanism Velocity Calculations
In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.
Series Inductance
In this learning activity you'll calculate the total inductance of a series circuit.
By Jessie Jelinski
2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a slotted block. A short quiz to test your ability to correctly read this information follows.
Frequency Dividers
In this learning activity you'll explore the operation of frequency division using several different types of counters.
Calculating Force for Punching
By Dave Hoffman
Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.
Pneumatic Cylinder Flow Control
Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.
Lathe Project: Thread Diameter Turning
