由题干关键词“a brick conduct electricity”定位到第三段“The brick battery relies on the reddish pigment(色素)known as iron oxide, or rust, that gives red bricks their color. The scientists pumped the bricks with several gases that react with iron oxide to produce a network of plastic ...
A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it. In a conductor, electricalchargecarriers, usuallyelectronsor ions, move easily fromatomto atom when voltage is applied. Most metals like copper are considered good conductors, while nonmetals...

Vegetable Electricity Conductors Potatoes, onions, and tomatoes conduct electricity quite well. Tomatoes (not vegetables, strictly-speaking ) are good conductors in the vegetable category, as they have the highest acidity level. Scientists have show potatoes work very well as batteries. Acids make ions...
It is the movement of electrons between the layers that explains this unusual property of graphite.Copper contains metallic bonds and so conducts electricity. Rubber contains covalent bonds and so does not conduct electricity. It protects the user from getting an electric shock....
Conductivity, the measure of a material’s ability to conduct electricity, is defined as the ratio of current density to the electric field that drives the current. It indicates how much energy can move through a system, such as an electrical circuit. This property also applies to the transmis...
Some animals require taller electric fences than others. The same goes for llamas and alpacas. They are known for their thick fur coats and other unique features. So, to keep them safe, you must plan your electric fencing thoroughly.
