- Conduction in n-type material is from free electrons.
- Conduction in p-type material is from holes (positive particles).
- The function of metal-oxide-semiconductor field-effect transistors (MOSFETs) depends on the voltage applied to the gate.
- Certain ranges of voltage allow no current to flow between the drain and the source. In this way, the MOSFET acts like an open switch.
- Another particular range of voltage allows current to easily flow from the source to the drain.
- When the voltage is in between the ranges of open and closed switch, the MOSFET can smoothly control the amount of current flowing.
- Bipolar Junction Transistors (BJTs) can act as either switches or current controls as well.
