![]() Thus, using the principle of Superposition,Įxample 7: Find v o in the network of figure 15 using Superposition Theorem. On the other hand, taking 10A source only Next, taking the -10V source only, for the current i_2 due to -10V source, we can writeĮxample 6: In the Π circuit shown in figure 14, find the current in the 2Ω resistor. Next, assuming 1A source active source only, with reference to figure 12(b).Įxample 5: In the circuit of figure 13, find R if i = 0.1A (Use Superposition Theorem). ![]() ![]() Next, taking the lower current source only (figure 9).Įxample 4: Find i o and i from the circuit of figure 11 using Superposition Theorem.Īssuming only 6V source to be active, with reference to figure 12(a). Let us first take the 2V source deactivating the current sources (figure 8). I.e., the current through the short circuit link is 7A.Įxample 3: Find v L in the circuit of figure 7 using Superposition theorem. Next, the sources 10V and 20V are considered and the circuit configuration is shown in figure 6. The circuit configuration for this case is shown in figure 5. Assume the link resistance to be zero.Īs the link resistance between the terminals a-b is zero, hence, the link is practically a short circuiting link and the current through the link is assumed to be I s.c. The current through 2Ω resistor is obtained asĮxample: 2 Using Superposition theorem, find the current through a link that is to be connected between terminals a-b. It may be observed that utilising the principle of Superposition, the net response can be obtained when both the sources (1A and 1V) are present. Next, let us assume the current source only (figure 3) Solution: Principle of Superposition is applied by taking 1V source only at first (figure2) The input is usually the allowed different classical configurations, but without the duplication of including both position and momentum.Ī pair of particles can be in any combination of pairs of positions.Example 1: Find I in the circuit shown in figure 1. The configuration space of a quantum mechanical system cannot be worked out without some physical knowledge. The pattern is very similar to the one obtained by diffraction of classical waves.Īnother example is a quantum logical qubit state, as used in quantum information processing, which is a quantum superposition of the "basis states" | 0 ⟩ ![]() However, unlike classical waves, quantum state amplitudes do not correspond to motion: adding two identical states is not meaningful.Īn example of a physically observable manifestation of the wave nature of quantum systems is the interference peaks from an electron beam in a double-slit experiment. Mathematically, the Schrödinger equation is linear, so any linear combination of quantum state solutions will also be a solution(s). Like waves in classical physics, any two (or more) quantum states can be added together ("superposed") and the result will be another valid quantum state. Measurements of quantum systems give a statistical result corresponding to any one of the possible states appearing at random. A quantum system interacts in ways that can be explained with superposition of different discrete states. It may not be known what they are at any given time, but that is an issue of understanding and not an issue of the physical system. In classical mechanics, things like position or momentum are always well-defined. Quantum superposition is a fundamental principle of quantum mechanics.
