Definitions Ideal Current Sources: provides a prescribed current flow to any circuit connected to its terminals irrespective of the voltage across its terminals. The voltage generated by the source is determined by the circuit connected to it. Electric Circuits (ENGR2790U) 51 of 310
Definitions Dependent (controlled) Source: its output (voltage or current) is a function of some other voltage or current in a circuit. i x and v x can be current and voltage in the circuit, respectively. Electric Circuits (ENGR2790U) 52 of 310
