Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
Learners examine three formulas than can be used to find dc power. Examples are given.
Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.
Students view the operation of a process controls system and examine the components and their function to prepare to work with the actual system.
Students read the steps for proper meter placement for the measurement of resistance, voltage, and current.
In this interactive object, learners read about the differences between push and pull manufacturing systems. A brief quiz completes the activity.
Learners read how quality can be built into a manufacturing process.
In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.
In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.
In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
Students practice reading a resistor's color code.
In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.
Students read about the various types of common components used in electronics and view their schematic diagram symbols. At the end of the lesson, students match the name of each component to its symbol.
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.
Students work six practice problems to determine the total capacitance of a series circuit. Immediate feedback is given.
In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
