Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
Kirchhoff's Current Law - Parallel Circuits
By Patrick Hoppe
In this learning activity you'll explore Kirchhoff's Current Law and view examples of its application.
By Terry Bartelt
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
Converting Numbers from Standard Form to Engineering Notation
By Ron Wallberg
Learners convert a number from standard form to engineering notation.
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.
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.
Charging Time Constants of an RC Circuit
In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.
Discharging Time Constants of an RC Circuit
In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.
