![]() If at least two independent sources have the same frequency (for example in power systems, where many generators operate at 50 Hz or 60 Hz), then superposition can't be used to determine average power. However, if the linear network is operating in steady-state and each external independent source has a different frequency, then superposition can be applied to compute the average power or active power. To calculate power we first use superposition to find both current and voltage of each linear element and then calculate the sum of the multiplied voltages and currents. being represented meanwhile by their respective internal resistances. In other words, the sum of the powers of each source with the other sources turned off is not the real consumed power. Superposition theorem states that In a linear network containing more. 1 I am having a problem applying the principle of linear superposition to the circuit below. If a number of voltage or current source are acting simultaneously in a linear network, the resultant current in any branch is the algebraic sum of the currents. Superposition works for voltage and current but not power. The theorem is applicable to linear networks (time varying or time invariant) consisting of independent sources, linear dependent sources, linear passive elements ( resistors, inductors, capacitors) and linear transformers. First, choose a power source and suppress all other power sources. It is used in converting any circuit into its Norton equivalent or Thevenin equivalent. With the superposition theorem, this will be simplified. This property is called the Superposition Principle, which can be defined as: if a system (function) responds to the input x1 with the output y1 and it responds to the input x2 with the output y2, it will respond to the sum of the inputs x1 + x2 with the sum of the outputs y1 + y2. The superposition theorem is very important in circuit analysis. The resultant circuit operation is the superposition of the various voltage and current sources. This procedure is followed for each source in turn, then the resultant responses are added to determine the true operation of the circuit.

I=0 internal impedance of ideal current source is infinite (open circuit)). Replacing all other independent current sources with an open circuit (thereby eliminating current i.e. ![]() V=0 internal impedance of ideal voltage source is zero ( short circuit)). Replacing all other independent voltage sources with a short circuit (thereby eliminating difference of potential i.e.To ascertain the contribution of each individual source, all of the other sources first must be "turned off" (set to zero) by:
