Q: A loop that consists of 200 ( N ) turns and an area ( A ) of 0.25 m2 is located in a downward-directed magnetic field ( B ) of 0.40 T. Additionally, the loop’s coils have a resistance ( R ) of 5.0 Ω. If the coils are crushed to an area ofContinue reading “MAGNETISM AND ELECTROMAGNETISM: Lenz’ Law”

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( RTH ) for an open circuit: The equivalent voltage will represent a system in which the voltage source ( Vs ) has been replaced by a voltage that “Continue reading “INTRODUCTION TO ELECTRONICS: Thevenin Voltage and Resistance Determination“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: Kirchhoff’s Laws ( Part 5 )
We are now ready to complete the Part 3 exercise using Kirchhoff’s Node and Loop Rules: Due to the presence of nodes at points C and E, differing current ( I ) values will be used to evaluate the voltage ( V ) drops that occur around each loop. There are three unique circuit pathwaysContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 5 )“
INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 4 )
Prior to completion of the previous lecture’s circuit problem, some additional practice identifying nodes and branches within a multi-loop circuit will be helpful: We begin our journey at the 3 V source located at the far-left side of the diagram. As the current ( I ) moves upward and to the right, we encounter ourContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 4 )“
INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 3 )
Thus far, we have used a single-loop series circuit to demonstrate the principles of Kirchhoff’s Loop Rule. What if, however, a circuit has multiple loops through which current ( I ) travels? To further complicate things, what if each loop contains a voltage ( V ) source? How will it be possible to determine theContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 3 )”
INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 2 )
The Loop Rule states that the sum of voltage ( V ) rises and drops around a closed loop must equal zero. This observation is an extension of the Law of Conservation of Energy which states that energy is neither created or destroyed, but it has the ability to change form. Furthermore, the direction thatContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 2 )”
