of element currents as circuit variables is convenient and reduces the
number of equations that must be solved simultaneously. Recall that a
loop is a closed path with no node passed more than once. A mesh is a
loop that does not contain any other loop within it.
Nodal analysis applies KCL to ﬁnd unknown voltages in a given
circuit, while mesh analysis applies KVL to ﬁnd unknown currents. Mesh
analysis is not quite as general as nodal analysis because it is only applicable to a circuit that is planar. A planar circuit is one that can be
drawn in a plane with no branches crossing one another; otherwise it is
nonplanar. A circuit may have crossing branches and still be planar if it
can be redrawn such that it has no crossing branches. For example, the | 4Ω v3 | Textbook Table of Contents | Mesh analysis is also known as loop analysis or the
