Learners are introduced to primary and secondary batteries. Examples are given.
Excel: Complex Subtraction
By Patrick Hoppe
Students view the steps for subtracting complex numbers in Excel.
By Terry Bartelt
In this learning activity you'll explore how a fuse de-energizes a parallel circuit when too many lamps are connected to a power outlet.
Identifying Engineering Notation
By Ron Wallberg
The learner will represent very large and very small numbers in engineering notation.
Interlocking Ladder Diagrams
Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.
Oscilloscope: DC Voltage Measurements
Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
Total Impedance of a Parallel Circuit Using Complex Numbers
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
Total Impedance of a Series Circuit Using Complex Numbers: Practice Problems
Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
Total Impedance of a Parallel Circuit Using Complex Numbers: Practice Problems
Students work six practice problems to determine the total impedance of a parallel circuit.
Total Impedance for Series-Parallel Circuits Using Complex Numbers
Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.
