Superposition theorem model problem in tamil

Superposition Theorem:
Some circuits require more than one voltage or current source.

For example, most amplifiers operate with two voltage sources.
When multiple sources are used in a circuit, the superposition theorem provides a methods for analysis.
Hence the superposition theorem is a way to determine currents in a circuit with multiple sources, by considering one source at a time and replacing the other sources by their internal resistances. Statement: In a linear, bilateral network having more than one source, the current and voltage in any part of the network can be found by adding algebraically the effect of each source separately.

Procedure:
i) Consider only one source E1 and replace the other source E2 by its internal resistance. If it is voltage source open circuit it and Current source short circuit it.
ii) Determine the current through load resistance.
iii) Then consider the other source E2 and replace the source E1 by its internal resistance.
iv) Determine the current (through load resistance.
v) Final load current is the algebraic sum of current supplied by E1 and E2
