1 Electricity And Electronics Fundamentals TECH 175 Fall Semester 2007 Chapter 6 Series Circuits 3 Series Circuits Two elements in a series – Connected at a single point – No other current-carrying connections at this point 4 Series Circuit A series circuit is constructed by connecting various elements in series 5 Series Circuits • Normally – Current will leave the positive terminal of a voltage source – Move through the resistors – Return to negative terminal of the source 6 Series Resistors The total resistance of a series configuration is the sum of the resistance levels. The more resistors we add in series, the greater the resistance (no matter what their value) The largest resistor in a series combination will have the most impact on the total resistance N T R R R R R R + + + + + = ... 4 3 2 1
