Why is the current always measured negative in LTSpice?

Web29. apr 2024 · The E and G sources depend on a voltage, and the F and H sources depend on a current. The I and V sources are independent. In SPICE, if you want something to depend on a current, SPICE uses voltage sources as the way to "measure" a current and then have something else depend on it. That is why the F source insists on the name of a voltage … WebSPICE is a powerful general purpose analog circuit simulator that is used to verify circuit designs and to predict the circuit behavior.
