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 1 )

Conventional current ( I ) within an electrical circuit travels from a positively charged anode to a negatively charged cathode terminal: In reality, electric field lines are what emerge from the positive terminal and terminate on the negative one; thus, negatively charged electrons actually flow in the opposite direction. Envisioning current as mobile positive chargesContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 1 )”
