You can insert a zero volt DC voltage source in any > branch and monitor the current through it. In gnucap, just ask for the current .. .probe tran i(d1) ij(d1) ic(d1) ic(q1) ie(q1) ice(q1) or whatever ... i(d1) = total current (ij + ic) ij(d1) = junction current ic(d1) = current in the diode's capacitance ic(q1) = current flowing into the collector ie(q1) = current flowing into the emitter. (probably negative) ice(q1) = current that flows into the collector through the transistor and out of the emitter There are lots more! Putting zero volt sources every place I want to measure current is a royal pain. I rarely want to know node voltages, except as a way to calculate what I really want. Why not let the simulator tell you what you really want? _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
