Detailed Solution
Download Solution PDFNodal Analysis is based on:
1. KCL
2. Ohm's law
KCL:
According to Kirchhoff’s current law (KCL), the algebraic sum of the electric currents meeting at a common point is zero. I.e. the sum of currents entering a node is equal to the sum of currents leaving the node. It is based on the conservation of charge.
By applying KCL,
i1 + i5 = i2 + i3 + i4
Ohm's law:
At constant temperature, the current flowing through a resistance is directly proportional to the potential difference across its end.
V = R I
Where V is the potential difference, R is resistance and I is current flowing.
