Current Source • A current source determines the current in the branch in which it is located. • The magnitude and the polarity of the voltage across it depend on the complete network.
Source Conversion • Source conversions are equivalent only at the external terminals
Current Sources in Series? • No way.
The two Approaches already learnt! • Reduce and Return Approach! • Simplest technique • Does not apply to more complex circuits.
Background KVL + KCL + Ohm’s law • sufficient in analyzing any resistive circuits • difficult to use as the complexity of circuits increased • Nodal Analysis • Mesh Analysis • developed based on Kirchhoff’s laws • provide two systematic methods for describing circuits
Steps of Mesh Analysis • 1. Assign a mesh current to each mesh. • 2. Apply KVL to each mesh --- express voltages in terms of mesh currents. • 3. Solve the resulting linear equations.
