_______ unknown voltage and _______equation.Solution
In nodal analysis, the number of unknown node voltages is always (total nodes – 1) because one node is taken as the reference (ground). The number of independent nodal equations is also equal to the number of unknown voltages. For a circuit with 10 nodes: ● Unknown voltages = 10 – 1 = 9 ● Equations = 9
