Loop/mesh and nodal analysis are methods of analysis that are used to find the unknown (voltage or current) in a circuit. Mesh analysis uses KVL to establish the equations for current. KVL and KCL are the two laws given by Kirchoff. The method using KCL is known as nodal analysis.

What are linear elements? Linear elements : In an electric circuit, a linear element is an electrical element with a linear relationship between current and voltage. Resistors are the most common example of a linear element; other examples include capacitors, inductors, andtransformers.

What is linear and nonlinear circuit? In simple words, a linear circuit is an electric circuit in which circuit parameters (Resistance, inductance, capacitance, waveform, frequency etc)are constant. A nonlinear circuit is an electric circuit whose parameters are varied with respect to Current and Voltage.

How many nodes are in a circuit? A node is the point of connection between two or more branches. A node is usually indicated by a dot in a circuit. If a short circuit (a connecting wire) connects two nodes, the two nodes constitute a single node. The circuit in Figure 1 has three nodes a, b, andc.
