A physical system would be meaningless without an observer. Conclusions about electrical systems are oftentimes made from the vantage point of the source ( Vs ), but this need not be the case. If a portion of a circuit is “ opened “, an observer can view the source and other components from the newlyContinue reading “INTRODUCTION TO ELECTRONICS: A Conceptual Analysis of Thevenin’s Theorem“

INTRODUCTION TO ELECTRONICS: Power in Series Circuits
Thus far, we have seen how the net resistance ( R ) to current ( I ) flow within a series circuit is the sum of all the resistors that are present: Rt = R1 + R2 + R3 +…Rn The voltage ( V ) drop that occurs as a coulomb ( C ) ofContinue reading “INTRODUCTION TO ELECTRONICS: Power in Series Circuits“
INTRODUCTION TO ELECTRONICS: Series Circuits
A series circuit is one in which electric current ( I ) travels along a closed path that does not split apart: *** Note: Conventional current consists of positive charges that flow from the positively charged anode to the negatively charged cathode. In reality, negatively charged electrons flow in the opposite direction. *** The diagram,Continue reading “INTRODUCTION TO ELECTRONICS: Series Circuits”
INTRODUCTION TO ELECTRONICS: Direct Current ( DC ) Voltage, Current, and Resistance
An introductory discussion of electronics would be remiss without a conceptual analysis of DC voltage ( Vdc ), current ( I ), and resistance ( R ). Most students readily adapt to teaching strategies that relate new topics to familiar themes and everyday life experiences. Visual aids are of preeminent importance to new and seasonedContinue reading “INTRODUCTION TO ELECTRONICS: Direct Current ( DC ) Voltage, Current, and Resistance”
