That was just the resistor load line that we were talking about. The load line usually a straight line represents the response of the linear part of the circuit connected to the nonlinear device in question. Zener Diode Series Resistor Calculator Load Line Analysis In Hindi Two Examples About Dc Load Line Common Emitter Circuit A load line represents the response of a linear circuit connected to the nonlinear device in question. Diode load line . Figure 2 13a shows a dc load line analysis of semiconductor diode in series with a 100 w resistance r 1 and a supply voltage e. The polarity of e is such that the diode is forward biased so a diode forward current i f flows. Line called the load line of possible values of current flow in the circuit. So thats how you do a graphical solution with a diode. The real diode is modelled as 3 components in s...
