INTRODUCTION TO ELECTRONICS: Parallel Circuits

We have previously seen how all of the current ( I ) within a series circuit will pass through each resistor ( R ) situated within it. The sum of the energy drops that a coulomb ( C ) of charge loses as it traverses a circuit is equal to the voltage ( V )Continue reading “INTRODUCTION TO ELECTRONICS: Parallel Circuits“

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 )”
