All conductors oppose electron current flow and warm up some, except the superconductors. That's because all conductors (save the superconductors) have some amount of resistance to the flow of current. That means any voltage applied will drive some current through a conductor, and the resistance will cause some amount of heating to take place. ======================================== Any conductor with a finite resistance (R > 0) will do. However, to be safe to the human operator and an efficient heat source, use a higher-resistance conductor wound in a spiral, such as the tungsten filament in an incandescent light bulb, which turns hot very quickly, but mostly emits infrared radiation (heat). Please check the related link for more information. ===============================
its ARTIFICIAL RADIOACTIVITY....because during bombarding, the element used,contains electrons which reacts with the non-radioactive substance which on further emits radiations.......
Metals form what is known as a metallic bond, which involves sharing electrons with the entire mass of metal, rather than forming molecules. The cloud of shared electrons easily absorbs and re-emits photons. That is why metals are so reflective.
it emits very high energy photons
Solar cells convert the sun's energy and emits electrons. After this takes place photons bounce off silicons atoms forcing them in a orderly manner so create a electric current.

In a battery, or voltaic pile, the negative terminal or wire, called the anode, emits electrons in an electrical circuit. The other terminal, called the cathode, collects electrons in an electrical circuit.
No.
The electrons of the atom move closer to the nucleus while the atom emits light.
There are three terminals on a transistor. Some have four, where the fourth is a screen.The normal three are Emitter, base and collector. The Emitter emits electrons, the collector collects them and the base controls the flow.
hot filament
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
An automobiel battery can explode. The battery emits a very small amount of Hydrogen gas which is highly flammable.

A filament is needed in a Cathode Ray Oscilloscope (CRO) to emit electrons in the cathode-ray tube. The electrons are accelerated towards the screen to create the electron beam, which is then deflected to produce the display. The filament heats up and emits electrons through thermionic emission, contributing to the functioning of the CRO.
