Dear Balakrishna,
Example 1: Find the three unknown currents () and three unknown voltages ( ) in the circuit below:
Note: The direction of a current and the polarity of a voltage source can be assumed arbitrarily. To determine the actual direction and polarity, the sign of the values also should be considered. For example, a current labeled in left-to-right direction with a negative value is actually flowing right-to-left.
Note that equations from KCL at node d and KVL to other loops are not independent. In general, if a circuit has n nodes and b branches, then there are independent node equations and independent loop equations. In other words, the sum of the number of independent loops and the number of independent nodes is always the same as the number of branches, i.e., the number of equations is always equal to the number of unknowns in the branch current method.
Now we can resolve the problem above using loop-current method:
For the first circuit, we apply KVL to the two loops to get
Assume node is the ground, and consider just as the only unknown in the problem. Apply KCL to node , we have
