INTRODUCTION TO ELECTRONICS: Voltage Divider Principle in Series-Parallel Circuits

The voltage-divider formula is expressed as follows: Vx = ( Rx / RT )( Vs ) This formula is used to determine how series resistors ( R ) split voltage drops apart as current passes through them. The net voltage drop across a series circuit’s resistors is always ( ignoring small losses ) equal toContinue reading “INTRODUCTION TO ELECTRONICS: Voltage Divider Principle in Series-Parallel Circuits“

INTRODUCTION TO ELECTRONICS: Series-Parallel Circuit Branch Identification

Due to the complexity of some series-parallel circuits, it takes time to appropriately identify circuit branches that negate the larger circuit being classified as purely series or parallel. There is no substitute for practice! Prior to using the appropriate mathematics and equations to solve series-parallel circuit problems, visual engagement with a wide variety of circuitContinue reading “INTRODUCTION TO ELECTRONICS: Series-Parallel Circuit Branch Identification“

INTRODUCTION TO ELECTRONICS: Two-Resistor Current Divider Derivation

We have previously seen how parallel circuits with two resistors ( R ) may be added together using specialized techniques. In one such case, the resistors had equal values, and in other cases, the values differed. These resistance values were then used to ascertain how currents ( I ) divide along each branch of theContinue reading “INTRODUCTION TO ELECTRONICS: Two-Resistor Current Divider Derivation“

INTRODUCTION TO ELECTRONICS: Series-Parallel Circuits

For the most part, the circuits we’ve encountered have been either series or parallel circuits with no deviance from either extreme. The only exception to this trend regarded circuits that had multiple voltage sources positioned within their multi-loop matrix. Adding to this complexity was the fact that these voltage sources could be oriented in anyContinue reading “INTRODUCTION TO ELECTRONICS: Series-Parallel Circuits“

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 )”
