The effect of connecting voltage sources in parallel to increase amperage to a load is presented.
What Is Current?
By Tim Tewalt, Patrick Hoppe
Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
Transfer Functions: The RL Low Pass Filter
By Patrick Hoppe
Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
Statics - Trig: Law of Cosines
By Steve Whitmoyer
In this interactive object, learners use the Law of Cosines to calculate forces.
Series-Opposing Zener Diodes
By Terry Bartelt
In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
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.
Series RLC Circuit Tic-Tac-Toe 1
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.
