DEFINITIONS OF BASIC ELECTRONIC COMPONENTS

BASIC ELECTRONIC COMPONENTS

1. RESISTOR

• A passive electronic component, manufactured with a specified amount of resistance.
• It is mainly used to control the flow of current.
• It allows desired amount of voltage in electronic or electrical circuits.
• Its unit is ohms.

2. INDUCTOR

• A passive electronic component, manufactured with a specified amount of inductance.
• When electricity is passed, the inductor stores energy in a magnetic field and induces the voltage.
• It is mainly used for tuning and filtering circuits.
• Its unit is Henry(H).

3. CAPACITOR

• A passive electronic component, manufactured with a specified amount of capacitance.
• It will charge or store energy in an electric field.
• It blocks dc current and allows ac current.
• Its unit is Farad(F).

4. TRANSISTOR

• A semiconductor component, used for amplification.
• It regulates the current and voltage flow in a circuit.
• It has three terminals for connection with external circuits.
• It acts as a switch for electrical and electronic signals.

5. DIODE

• An electronic component, consisting of two terminals.
• Diode is used to convert ac voltage to dc voltage i.e., rectification.
• It allows current in one direction while it blocks current in other direction.
• The diodes are used in Power supplies.

6. INTEGRATED CIRCUITS (IC'S)

• It is just a packaged electronic circuit.
• They are made up of semiconductor material normally silicon.
• There are thousands of resistors, capacitors and transistors  fabricated on a tiny single chip of silicon.
• IC's are normally used in all electronic equipments like computers, mobile phones etc.
