Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of
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
Doping of Semiconductors
materials which can conduct electricity better than insulator, but not as well as conductors.
The process of adding of a certain amount of specific impurities atoms in the pure semiconductor.
when 4 electrons in outermost orbit.
These are the characteristics of pentavalent impurities except
•5 valence electron.
•contributing extra free electrons.
•produce n-type semiconductors.
•produce p-type semiconductors.
These are the characteristics of Trivalent impurities except
•3 valence electrons
•produce p-type semiconductors
•producing a "hole".
Boron, aluminium and gallium are the examples.
Antimony, arsenic, and phosphorus are the examples
which statement is correct? (the dark circles represent the electrons)
p-type of the diode is connected to the negative terminal.
Electron moves across the p-n junction, makes the diode forward biased
current will not flow in the circuit
reverse biased circuit
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.
The diagram is a process
of doping
of adding impurities
of half-wave rectification
of full-wave rectification
This is a graph that is seen on CRO. How is it change after full wave rectification process?
Choose the diagrams that show smoothing process has occured
