Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series RLC Circuit Tic-Tac-Toe 2
By Terry Bartelt
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 above resonance.
Oscilloscope Frequency Measurements
Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
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.
Graphical BJT/JFET Transistor Biasing
By Roger Brown
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
Learners observe animations showing how data is converted between serial and parallel flow.
Series-Parallel Practice Problems Circuit 4
By Patrick Hoppe
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then 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.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
Total Resistance in a Parallel Circuit
The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.
