The nodal conductance matrix and mesh resistance matrix of a memoryless circuit without
any dependent sources in it (i.e., a pure resistive circuit) are symmetric matrices. Reciprocity
Theorem for resistive circuits is a restatement of this fact.
Let us consider a pure resistive circuit with only one independent current source
driving it as shown in circuit of Fig. 5.7-1(a).
A current source of value Iis connected across a node-pair ‘i’ and ‘j’. Two other
nodes – ‘k’ and ‘m’ – form a node-pair across which the voltage can be measured. There is
no other independent source or dependent source inside the circuit in the box.
