diode
semiconductor
conductor
insulator
superconductor
Which is not one of the properties of semiconductor?
4 electrons in outermost orbit, in covalent bonding.
atoms vibrate causes electron to break free from the bonds.
Electron free leaves hole.
Semiconductor has 2 types of charge carriers.
all of the above are the properties of it
what is the meaning of rectification?
a process of smoothing using a capacitor
a process of adding impurities to pure materials
a process of converting an alternating current into a direct current by using a diode.
