This is known as Superposition Theorem and is valid because of linearity Use superposition to analyze circuits that have lots of voltage and current sources. As an example, consider the circuit below: We can Thevenin theorem, Dependent sources, Loop analysis, Node analysis, Equivalent networks. Like Thevenin's Theorem, it simplifies the circuit one needs to study and dramatically reduces potential calculation errors. This is basically what the Superposition Theorem states. Turn off one of the sources – the order doesn't matter. This theorem is applied when solving a circuit with more than one source to determine voltage/current for a specific element. (c) Circuit with current source connected. Norton's Theorem: Any one-port (two -terminal) network of resistance elements and energy sources is equivalent to an ideal current source $I_N$ in parallel with a resistor $R_N$ , where. Let's explore this with the following example: For the circuit on Figure 4 calculate the voltage v. - Compute the Thevenin equivalent resistance, R.
