Compute the currents based on voltage differences between nodes. Nodal Analysis Example Label the nodal voltages. In loop analysis, the unknowns are the loop currents. Mesh analysis means that we choose loops that have no loops inside them. For N independent loops, we may write N total equations using KVL around each loop.
Current sources provide constraint equations.
Solve the equations to determine the user defined loop currents. Solve for I 1 and I 2 . In any linear circuit containing multiple independent sources, the current or voltage at any point in the network may be calculated as the algebraic sum of the individual contributions of each source acting alone. Calculate the contribution of this particular voltage or current source to the desired output parameter. Compute the open circuit voltage, V OC .
