What is the full form of LED, LCD, MCB, USB, CFL, CFC?
Answer:
LED – Light Emitting Diode
The LED is a PN-junction diode that produces light as it passes via an electric current in the forward path. Recombining the charge carrier occurs in the LED. The N-side electron and the P-side hole are mixed and provide the energy in the form of light and heat.
LCD – Liquid Crystal Display
LCD is a flat – panel display system that is primarily seen in Television and computer screens, which is also used by cell phones presently. LCD consists of millions of pixels created from crystal and organized in a rectangular pattern on the LCD panel. For LCD, it has backlights that bring light to every pixel. Every pixel has a sub-pixel (RGB) red, green & blue which can be switched off or on. When all subpixels are switched off, it is black while all subpixels are switched on a hundred per cent then it is white.
MCB – Miniature Circuit Breaker
MCB is a kind of electronic switch that functions automatically. It can detect a problem occurring inside a circuit by identifying the extreme amount of current flow in the circles. The MCBs are a better choice because it needs to be reset by users and it starts working again. It is designed to protect against faults caused by overheating.
USB – Universal Serial Bus
USB is a common platform that allows communication between devices and a host controller such as a PC (computer). Such buses are handy when we are concerned about how to link the computer to the electronic system we have. They are used for networking, contact, or power supply purposes.
CFL – Compact Fluorescent Lamp
CFL is an energy-saving bulb that consumes much less energy than the conventional incandescent lamps. It is made of a glass tube, along with two electrodes. The glass tube contains a mixture of argon gas & mercury vapour and is filled with phosphorus on the inner surface.
CFC – Chlorofluorocarbons
CFC are gases used for various purposes including solvents, refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine. They were much used in the middle 20th century, replacing chemicals that were toxic or flammable or had traits that were generally harmful to human health.
