In some network, in which some of the voltage sources or current sources are controlled by changing of current or voltage elsewhere in the circuit. Such sources are termed as “Dependent or Controlled sources”.
There are four types of dependent sources.

Dependent Voltage Source(DVS)

Dependent Current Source(DCS)
- CDVS( Current DVS)
- CDCS(Current DCS)
- VDVS(Voltage DVS)
- VDCS(Voltage DCS)
