two-resistor current divider formula

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: The Balanced Wheatstone Bridge

The voltage ( V ) drops across parallel-circuit resistors ( R ) are equal in magnitude; conversely, the currents ( I ) traveling through parallel branches may or may not be the same. For this reason, parallel circuits are sometimes referred to as being current dividers. Take the following diagram into consideration: Since the R1Continue reading “INTRODUCTION TO ELECTRONICS: The Balanced Wheatstone Bridge“

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“
