In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.
Hydraulic Oil Contamination
By Terry Bartelt, Stephen Schneider
In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.
Ohm's Law Practice Problems #4
By Patrick Hoppe
Learners review Ohm's Law and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Parallel Circuit Analysis Practice Problems: Circuit #6
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Wiring Integrated Circuits
By Terry Bartelt
Instructions on how to wire an integrated circuit are given.
Financial Statement Analysis
By Lynette Teal
Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.
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.
Eddy Current Demonstration
Learners view two animations that show the effects of eddy currents.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-30XIIS Calculator)
Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.
