Hi to all, Based on my understanding bipolar transistors pnp or npn they are normally off until apply voltage to the base to turn it on but FET transistors are opposite they are normally on until apply power to the Gate and Source to turn it off. My question is: Are all FET, JFET, MOSFET and etc FET transistors work the way I described above or I misunderstood? Any feedback will appreciate.
