Three terminals means three types: common emitter, common base, common collector/emitter follower. This applies to a MOSFET as well, common source, common gate, common drain/source follower. ca non resident tax form

"WebFeb 10, 2024 · To work as an open switch, a BJT operates in cut-off mode, here there is zero collector current, meaning ideally zero power is consumed by the BJT. On the other hand, to work as a closed switch, a BJT works in saturation mode, there are a high collector current and zero collector voltage, meaning ideally there is zero power consumed by the BJT.
