Circuits Calculus design!! Hey Everybody!! i have always wonder how do you calculate complex circuits!!!....i mean, when you`re in college they teach you how to solve by Nodes, kirchoff, thevenin and norton Resistive circuits and RLC circuits......but after that they never teach you how to calculate and design your own circuits.... my question is....how do you calculate the values of the components in a complex circuit??? for example, check this circuit of a voltaje regulator.....how do you calculate its values??? thanks!!
