Learners convert a number from standard form to engineering notation.
Voltage Sources in Series
By Terry Bartelt
In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.
RC Time Constant
By Tim Tewalt, Patrick Hoppe
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.
Learners view animations showing methods of measuring the pH level of a solution using litmus paper and electronic instruments.
Sizing Motor Overloads
By Terry Bartelt, Pat Jensen
Learners use the National Electrical Code to determine the size of a motor overload protection device.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Learners observe animations showing how data is converted between serial and parallel flow.
Voltage Drops in a Series Circuit
Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.
Kirchhoff's Voltage Law
By Patrick Hoppe
Students read a definition of Kirchhoff's Voltage Law and view examples of its use.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
Rounding to the Correct Decimal Place
You'll choose the number that is rounded to the correct decimal place: whole, tenth, hundredth, or thousandth.
Rounding Decimal Numbers - 2 Choices (Set 2)
You'll determine which of two options is the correct choice for rounding a given number to the nearest tenth, hundredth, or thousandth.
