Hi all, I know about Kirchhoff's voltage and current laws when it comes to simple circuits with two-terminal elements and junctions/nodes of branches. However I'm curious how KVL and KCL are applicable to multi-terminal elements? Does KCL apply to any junction of branches no matter what that junction is, an element/black box/IC/simple node? How does KVL apply to loops with multi-terminal elements? Does Ohm's law or element law hold true for multi-terminal elements? For instance a transistor in simple common emitter configuration, if we apply KVL to the collector-emitter loop to calculate the Vce (voltage between collector and emitter) can we dvide this voltage by the resistance measured between the collector-emitter terminals to find the current? And if so which current would this be, the collector currant or the emitter? Thanks.
