Many simple circuits can be categorized as being either a series circuit, parallel circuit, or a combination series-parallel circuit. To the contrary, analysis of Wheatstone bridge circuits is comparatively difficult, because no clear cut series-parallel relationship exists between its component resistors: Thevenin’s theorem enables us to analyze the circuit with convenience via removal of theContinue reading “INTRODUCTION TO ELECTRONICS: Thevenizing a Wheatstone Bridge Circuit”

INTRODUCTION TO ELECTRONICS: Thevenin Voltage and Resistance Determination
Now that a conceptual understanding of Thevenin’s theorem has been established, we are ready to determine the Thevenin voltage ( VTH ) and Thevenin resistance ( RTH ) for an open circuit: The equivalent voltage will represent a system in which the voltage source ( Vs ) has been replaced by a voltage that “Continue reading “INTRODUCTION TO ELECTRONICS: Thevenin Voltage and Resistance Determination“
INTRODUCTION TO ELECTRONICS: A Conceptual Analysis of Thevenin’s Theorem
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: Thevenin’s Theorem and Equivalent Circuits
In the diagram below, a circuit is placed within a box. Next, the circuit is opened on the opposite end of the voltage source inside so that two output terminals are visible. The current ( I ) and potential difference ( V ) in relation to the newly created output terminals is then measured: TheContinue reading “INTRODUCTION TO ELECTRONICS: Thevenin’s Theorem and Equivalent Circuits“
