In this interactive object, learners examine simplified sampling plans and tables based on the ANSI/ASQ Z1.4 standard. An exercise completes the activity.
Basic Elements of Dimensions Used in Engineering Drawings
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
Students examine the four factors that affect resistance of a wire: temperature, length, diameter, and the type of material from which it is made. A short quiz completes the activity.
Financial Statements: What Are They? What Do They Mean?
Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.
Current and Voltage Parameters of Digital Circuitry (Screencast)
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
