What is an SCR (silicon controlled rectifier)?

It is a type of rectifier, made of silicon, that is used as a control. The SCR is a semiconductor used to control current through small current.

What is an integrated circuit?

An integrated circuit is a microchip that is a small semiconductor used to relay information via specific electrical characteristics.

What is a semiconductor?

Elements that allow the circulation of electricity.

What is a chip?

A chip is a piece of silicon with an electronic circuit. It describes an integrated circuit, or IC, such as a central processor or a graphics chip.

What does the gate in an SCR do?

The gate is in charge of controlling the flow of current between the anode and cathode. It works basically as a controlled rectifier diode allowing the circulation of the electric flow in one direction.

What is the anode and the cathode?

An anode is an electrodethat loses electrons and rises it’s oxidation state..

A cathode is an electrodethat wins electrons and lossesIt’s oxidation state.

What is a diode?

Electric component that Allows the electric circulation in one direction.

What are some of the advantages of using integrated circuits?

• Few number of connections.• They are small.• Few wight and space because

they are miniaturized.• Require few power.• Minimum number of external

connections.

What is the size of a silicon chip?

The sizes of silicon chips are:

SSI - small scale integrationMSI - medium scale integration

LSI - large scale integration

VLSI - very large scale integration

ULSI - ultra large scale integration

GSI - gigascale integration
