Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
The TI-86 Calculator: The Square Root Function
By Patrick Hoppe
Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.
ElectroMagnetic Radio Waves
By Terry Bartelt
In this animated object, learners examine how magnetic waves are transmitted as radio signals.
Series Circuit Analysis Practice Problems: Circuit #10
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.
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.
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.
Oscilloscope Phase Shift Measurements
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Energizing Time Constants of an RL Circuit
In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.
De-Energizing Time Constants of an RL Circuit
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
