Electronics for beginners

Electronics is one of the most powerful and enjoyable hobbies around. There is little you can't do or improve with a electrical circuit and a few chips. This guide will hopefully help you learn the basics of electronics, from basic static electricity to complex digital electronics. It is designed to be for beginners, so start at the first page and go through them one by one. While we have put a bit of effort in to making all our information as accurate and safe as possible, electricity is dangerous you play with it at your own risk so you should exercise caution and know what you are doing.

me too ;)

Calculation of voltage depends on the circuit,not that an introduction of an elemnt will increase or decrease it

Its very well explained here by "liljay22776"

By Ohm's law V=IR where,

V=Voltage
I=Current
R=Resistance

or R=V/I thus Resistance is inversely proportional to Current "Across the resistor"

Meaning Resistance decreases Current.
Resistance simply means, Resistance to Current... ;)

Is it clear now..?

i like men

this is good but if there is more information about current voltage that is better, so when i see that type of current defination i understand it and also i pick very fast.

Scientists demonstrate world's fastest graphene transistor; holds promise for improving performance of transistors
IBM researchers have demonstrated a radio-frequency graphene transistor with the highest cut-off frequency achieved so far for any graphene device -- 100 billion cycles/second (100 GigaHertz). The high frequency record was achieved using wafer-scale, epitaxially grown graphene using processing technology compatible to that used in advanced silicon device fabrication.

Super material will make lighting cheaper and fully recyclable
With the use of the new super material graphene, Swedish and American researchers have succeeded in producing a new type of lighting component. It is inexpensive to produce and can be fully recycled.

New system provides hybrid electric autos with power to spare
An advancement in hybrid electric vehicle technology is providing powerful benefits beyond transportation.

Computers that use light instead of electricity? First germanium laser created
Researchers have demonstrated the first laser built from germanium that can emit wavelengths of light useful for optical communications. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity.

New simulation tool could shorten manufacturing design process
Researchers have demonstrated they were able to speed up SystemC based simulation by factors of 30 to 100 times that of previous performances. SystemC is often used to shorten manufacturing design cycles to improve the time it takes to bring a product to the marketplace.
