Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.
Students read the rules used in multiplying and dividing signed numbers. They view examples and work practice problems.
Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.
Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.
Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.
Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.
Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.
In this learning activity you'll review scientific notation and practice expressing numbers larger than 1.
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
In this learning activity you'll read an explanation of scientific notation and practice expressing numbers smaller than 1 in scientific notation.
Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
In this learning activity you'll review an explanation of scientific notation and complete exercises to convert scientific notation to ordinary numbers.
