1. Condition: It is the situation where there is a current source in any mesh as in Figure 7.20. In the circuit in the figure, there is no need to write an additional environmental equation for the 2nd mesh. Because there is 10A current produced by the independent current source from this mesh. 20 V www www 10 A

ACTIVITY No. 6 Nodal Analysis ОВJECTIVE The study of nodal analysis is the objective of this exercise, specifically its usage in multi-source DC circuits. Its application to finding circuit currents and voltages will be investigated. THEORY OVERVIEW Multi-source DC circuits may be analyzed using a node voltage technique. The process involves identifying all of the circuit nodes, a node being a point where various branch currents combine. A reference node, usually ground, is included. Kirchhoff's Current Law is then applied to each node. Consequently a set of simultaneous equations are created with an unknown voltage for each node with the exception of the reference. In other words, a circuit with a total of five nodes including the reference will yield four unknown node voltages and four equations. Once the node voltages are determined, various branch currents and component voltages may be derived. EQUIPMENT (1) Adjustable DC Power Supply (1) Digital Multimeter (1) 4.7 k2 (1) 6.8 k2…

Which of the following is an accurate statement? A There could be two or more reference node in a given network. (B The principal node is considered as lower potential with respect to reference node. Any principal node can be used as reference node. The potential between two principal nodes is zero.

What is a Linear Circuit? Simply we can say that the linear circuit is an electric circuit (Links to an external site.) and the parameters of this circuit are resistance, capacitance, inductance and etc are constant. Or we can say the parameters of the circuits are not changed with respect to the voltage and current is called the linear circuit. What is a Non-Linear Circuit? The non-linear circuit is also an electric circuit and the parameters of this circuit differ with respect to the current and the voltage. Or in the electric circuit, the parameters like waveforms, resistance, inductance and etc are not constant is called as Non- linear circuit.   Question: Is it possible to apply superposition theorem to nonlinear circuit? If yes, why? and if no, why?
