Teachoo provides the best content available! If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. One should remember that ions are good conductors of electricity. Most often, gold is used as plating for connectors. The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Comparatively, electrical conduction of this metal is not as good as that of the metals like copper or silver but, is much better when compared to semiconductors. So, it conducts electricity much more actively than semiconductors but, less than good conductors. But, If we attach wires to the plastic part of the screwdriver, the bulb will not glow. Ions are good conductors of electricity. The vegetable is actually a mixture of water, salt and starch. It contains lot substances that conduct electricity. Gold is not only a good conductor of electricity, but also a good conductor of heat. One may be surprised to know that soda is a good conductor of electricity. When a salt is dissolved in water, it releases ions. Uranium is a metal and is a good conductor of both heat and electricity. Copper is a good conductor of heat and electricity.
