Basic Electronics

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

These are the characteristics of Trivalent impurities except

• •3 valence electrons

• •produce p-type semiconductors

• •producing a "hole".

• Antimony, arsenic, and phosphorus are the examples

The characteristics of p-type semiconductors is includes

• Majority carriers are electron

• Has tendency to gain electron

• Has tendency to donor electron

• Easy to conduct electricity

What is the most common semiconductor material used for producing integrated circuits

• Quartz

• Silicon

• Diamond

• Tantalum

Name this electronic component

• Capacitor
• Fixed Resistor
• Potentiometer
• Transistor

How is conduction increased in an p-type semiconductor?

• by increased applied electrical field

• by decreased applied electrical field

• by the availability of extra holes

• by the availability of donor electrons

The potential difference created across the P-N junction due to the diffusion of electrons and holes is called___________

• potential barrier

• back emf

• instantaneous speed

what is a diodes function

• allows current to flow in one direction

• allows current to flow in two directions

• is a resistor

when a Diode is used as a half wave rectifier ....

• It rectifies only one half of the input AC signal

• It rectifies both the halves of the input AC signal
