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.

Actually, looking at the diagram you might say that it's at about 4.1Hz. This is an important thing to consider.
In the electromagnetic world cycles do not represent transfer of energy but rather a change of state. If you were to increase this to 60Hz you would not see an increase in the energy, just the number of cycles. You might see an increase in the energy (voltage) dependent upon the length of the line the electricity was run through, however this would not be a direct product of the frequency rather the ability of your conductor to carry a DC charge (resistance).
Aren't the Ammeter and Ohmeter backawards?
capacitor is descharging in time ... or if you want a quick descharging just make a short to the ground
I need to find an atomic model of Iron. Help, anyone?
can any one suggest me about practical testing of these electronics components or there is any site related to it.
thanks in advance

Method For Integrating Nanowire Devices Directly Onto Silicon Developed
Scientists have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. The fabrication technique could yield low-cost, scalable nanowire photonic and electronic circuits.
Modern Ceramics Help Advance Technology
Many important electronic devices used by people today would be impossible without the use of ceramics. A new study illustrates the use of ceramic materials in the development of technological devices, including mobile communication and ultrasonic imaging.
Smart Miniature Pump Could Deliver Medicine
An innovative micro-pump makes it possible for tiny quantities of liquid -- such as medicines -- to be dosed accurately and flexibly. Active composites and an electronic control mechanism ensure that the low-maintenance pump works accurately -- both forwards and backwards.
Nano-designed Transistors With Disordered Materials, But High Performance
The Holy Grail for transistor designers has been the requirement to be able to get high performance at reduced costs over very large substrate areas. Transistors on cheap and flexible substrates like glass and plastics are currently unable to deliver such performance and therefore do not lend themselves to seamless monolithic integration of increased electronic functions on human interface devices (displays and sensors).
Graphene-based Gadgets May Be Just Years Away
Researchers have produced tiny liquid crystal devices with electrodes made from graphene -- an exciting development that could lead to computer and TV displays based on this technology. They report on the use of graphene as a transparent conductive coating for electro-optical devices -- and show that its high transparency and low resistivity make it ideal for electrodes in liquid crystal devices.
