superposition can find the voltage and current effect of each source to a particular branch of the circuit and we can calculate the total effect of the sources to know the effect of the total sources to that branch

State the principle of superposition of waves?

superposition of waves is the vector sum of the individual displacements

What is the law of superposition theorem?

Superposition is where an object can be in two or more states, places, or realities, at the same time. This occurs at the subatomic level and is an important factor in Quantum mechanics. Superposition does not happen to objects that are at the atomic level or higher. They obey Newtonian physics, and each object can only be in one state, place, or reality at any given time. A scientist by the name of Erwin Schrödinger tried to explain the difference between the two in a story called: Schrödinger's cat. ---- ---- == == == == ----

What is the application of superposition theorem in your daily life?

There are numerous applications. The easiest and most commonplace I can think of right now, is the condition of not being able to hear anything clearly when more than two people speak loudly at the same time. This occurs due to destructive and constructive interferance, which is caused by superposition.Another view:The principle of superposition is a consequence of the linearity of the underlying wave equations for light (and sound, though only approximately). This means that there is no scattering of light by light: two wave packets can travel right through each other without interacting.As far as your daily life goes, this means that you can look at someone across the room without their image becoming distorted by the (very many) electromagnetic waves flying around the room in various directions: e.g. radio waves, microwaves (e.g. from Bluetooth devices), infra-red from warm bodies, visible light and so on.If light violated the principle of superposition to any great degree, vision would be far less useful.

What is Linear superposition principle?

when more input force(s) are given,it results in the addition of or sum of input forces and no new forces are created.It is called linear superposition principle.

Is it true During interference the new wave exists only during the overlapping of the first two waves?

There really is no "new wave" - just a superposition of the existing wave. Any such superposition is temporary.
