A circuit with all components connected end-to-end such that there is only one path of current flow is a series circuit.
RESISTANCE IN SERIES CIRCUITS
The total resistance is the sum of the individual resistances in a series circuit.
CURRENT IN SERIES CIRCUITS
The same current flows through all components in a series circuit. The total current is equal the current flow of any individual component.
VOLTAGE IN SERIES CIRCUITS
The total voltage is the sum of the voltage drop of each component in a series circuit.
The voltage drop across a resistor in a series circuit is proportional to the ohmic value of the resistor.
POWER IN SERIES CIRCUITS
The total power is the sum of the individual power of each component in a series circuit.
SERIES CIRCUIT ANALYSIS
VOLTAGE POLARITY AND REFERENCES
Polarity (whether a point has positive or negative voltage potential) is relative based on the point of reference in a circuit.
An electrical ground utilizes the earth or an equipment chassis as a reservoir of charge, which is normally considered to be zero volts.
TROUBLESHOOTING SERIES CIRCUITS
Troubleshooting is the process of locating faulting components or connections within a circuit.
Troubleshooting Open Circuits
An open circuit has infinite resistance. In a series circuit an open causes current to cease to flow through any of the components.
Troubleshooting Short Circuits
An short causes current to bypass has infinite resistance. In a series circuit an open causes current to cease to flow.
