FIRST ORDER CIRCUITS: SOURCE FREE RC AND RL CIRCUIT

FIRST ORDER CIRCUIT
-A circuit that can be simplified to a Thevenin's or Norton's equivalent connected to either a single equivalent inductor or capacitor.

THE SOURCE-FREE RC CIRCUIT
-an electric circuit composed of resistors and capacitorsdriven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.

IN SOLVING THE RC CIRCUIT

The time required for the voltage to fall to is called the RC time constant and is given by

SOURCE FREE RL CIRCUIT
-is an electric circuit composed of resistors and inductorsdriven by a voltage or current source. A first order RL circuit is composed of one resistor and one inductor and is the simplest type of RL circuit.
