theory - Why are dependent sources not disabled with the …
If you disabled dependent sources when modeling the contribution of a dependent source to the circuit, they'd have no effect on the circuit. If you did another round of superposition to get the contribution from the dependent source, there'd be no output because there wouldn't be any independent source present to drive the dependent source's input.
circuit analysis - Superposition principle: Dependent sources …
From this limited survey, it is clear that circuits texts either state or imply that superposition of dependent sources is not allowed. The author contends that this is a misconception. As a simple example using superposition of a dependent source consider the following circuit: simulate this circuit – Schematic created using CircuitLab

2019年11月19日 · Thus, for the specific case you mention, the independent source set to 0 makes the dependent source same as an open circuit. But that's only because you got a dependent current source. This is not the case for dependent voltage sources, which, when set to 0, are indistinguishable from a short circuit. \$\endgroup\$ –

2024年6月9日 · The rest of the circuit, however, has four sources: two independent voltage sources and two dependent current-controlled voltage sources. The circuit is redrawn to simplify the structure. How could I further go about trying to simplify the circuit so I …
In superposition theorem, can I activate multiple sources together?
2023年1月13日 · Yes, you can activate two sources at a time in the circuit and set the third source to zero to apply superposition theorem. AC sources use steady state analysis and DC sources require solving integro differential equations. You can superimpose the currents and voltages. They would have a offset which is due to the 10V DC supply.
basic - Dependent sources - Electrical Engineering Stack Exchange
Why are dependent sources never deactivated in application of this theorem? When solving a network with multiple independent sources, we can use the superposition principle. This means deactivating all except one independent source one by one and solving the network for each case, then combining the results to get the solution for the network ...
circuit analysis - Why superposition theorem fails here? - Electrical ...
2016年12月12日 · In a real circuit, connecting two sources in parallel would lead to a circuit with a very small, but still non-zero resistance between them, which would result in one of the sources (the one with a slightly lower voltage) actually sinking current, but the current through the 5 ohm resistor would only depend on the voltage of the right source.
AC circuit with two sources - Electrical Engineering Stack Exchange
They are AC (frequency dependent) signals or otherwise the inductor will be shorted, and the capacitor opened (assuming the circuit has been in this position for along time and no switching mechanism has occurred.) The zero in the independent sources up there are just an indication of the phase shift. The sources are in-phase.
