Many simple circuits can be categorized as being either a series circuit, parallel circuit, or a combination series-parallel circuit. To the contrary, analysis of Wheatstone bridge circuits is comparatively difficult, because no clear cut series-parallel relationship exists between its component resistors: Thevenin’s theorem enables us to analyze the circuit with convenience via removal of theContinue reading “INTRODUCTION TO ELECTRONICS: Thevenizing a Wheatstone Bridge Circuit”

INTRODUCTION TO ELECTRONICS: The Unbalanced Wheatstone Bridge and Sensor Technology
A transducer is an electronic device that measures physical parameters such as mechanical strain, pressure, optical density, and/or temperature. If temperature is being measured, an instrument called a thermistor acts as a variable resistor at the R1 location of a Wheatstone bridge. At a known neutral temperature, a zero reference voltage ( Vout ) valueContinue reading “INTRODUCTION TO ELECTRONICS: The Unbalanced Wheatstone Bridge and Sensor Technology“
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“
