anonymous · Answer

basically, mesh/nodal analysis are very useful in electrical circuit analysis, this will aid the designer to find the currents and voltages present within the circuit... circuits utilizing diodes, transistors and other devices can be converted or interpreted into their equivalent circuits with simply resistor, capacitor or inductor equivalents, then applying mesh/nodal analysis depending on configuration will allow you to obtain the relationship between currents, voltages, and equivalent components... example relationships where the so known Shockley's Equation... for JFET devices...
