4.4: Dependent Sources

INDEPENDENT VS. DEPENDENT SOURCES

1. INDEPENDENT SOURCES

a) Independent voltage source:

Two terminal element that maintains a specified voltage between its terminal.

b) Independent current source:

Two terminal element that maintains a specified current between its terminal.

2. DEPENDENT SOURCES

Generate voltage or current based on the voltage or current at some specified location in the circuit. It divides into four types:

a) Voltage controlled voltage source: V = uVx

b) Current-controlled voltage source: V = R(ohms)Ix

c) Voltage-controlled current source: I = G (1/ohm)Vs

d) Current-controlled current source: I = BIx
