Question

Advantages and disadvantages of superposition theorem

Answer 1

The superposition theorem states that the total current in any part of a linear circuit equals the algebraic sum of the currents produced by each source separately. In order to evaluate the separate currents to be combined, all other voltage sources should be replaced by short circuits and all other current sources should be replaced by open circuits.

Advantages - It is applicable to the elements of the network as well as to the sources. It is very useful for circuit analysis. It is utilized to convert any circuit into its Thevenin equivalent or Norton equivalent.

Disadvantages - Superposition is applicable to current and voltage but not to power. It cannot be used for unbalanced bridge circuits.

Answer 2

Well, Superposition theorem tells about the total current in a circuit.
Advantages:
1) This theorem provide basis for the analysis of circuit .
2) Superposition theorem used for application of network sources element.
3)Any circuit can be converted into thevenin equivalent using this theorem.

Disadvantages:
1) As this theorem  is based on the linearity so it is not possible to calculate the power using this theorem.
2) in case of un-balanced bridge circuit this theorem can't be use
3) The one big limitation is that this theorem only applied to the circuits with more than one source.
