The effect of connecting voltage sources in parallel to increase amperage to a load is presented.
Current Source Approximations
By Patrick Hoppe
Learners examine first and second approximations and view examples of a "stiff" current source.
Op Amps 3: The Inverting Amplifier
By Todd Van De Hey
Describe the inverting op-amp configuration and calculate the circuit gain.
Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.
Voltage and Current Amplitudes in a Parallel LC Circuit
By Terry Bartelt
In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
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.
