In general, metals make good conductors of electricity. These include copper, gold, silver and aluminum. Copper is a common conductor of electricity used in industrial applications because it is inexpensive to acquire, especially in comparison to gold and silver. Aluminium is not as efficient in conducting electricity as copper is.
Conductors are so-named because they permit the flow of electricity, or the movement of electrons from one atom to another. While metallic substances make good conductors of electricity, non-metallic substances usually do not. These include air, glass, wood, plastic and rubber. Materials that are not good conductors of electricity are commonly known as insulators. Insulators restrict the flow of electrons from one atom to another. Some of the strongest insulators include glass, pica and quartz. Insulators are used where it is necessary to protect or shield from electricity, such as electrical cords. The covering of the cord is the insulator, which prevents electricity from flowing to the outside of the cord. The inside of the cord contains the conductor, which allows electricity to flow and the appliance to function.The relationship between conductors and insulators can be summarized in terms of their resistance to electrical current. Conductors have low resistance to electrical current. Insulators have high resistance to electrical current.Learn More
A simple electrical circuit contains four parts: a power source, a load, connectors and a switch. The power source provides energy for the electricity to travel along the circuits and the load is the device that the circuit is designed to power.Full Answer >
Wiring two 12-volt batteries together depends on the application it needs to be used in. If double the voltage from 12 to 24 volts is needed , the batteries are wired in series (negative, positive wired to negative, positive). If 12 volts are needed, the batteries are wired in parallel (positive wired to positive and negative wired to negative).Full Answer >
Static electricity results from an imbalance between positive and negative charges in an object, according to the Library of Congress. It affects daily life in numerous ways, such as causing hair to rise when a person removes his hat as the electrons get transferred from the hat to the hair.Full Answer >
Hydroelectric power is the converting of energy coming from running water to produce electricity. Hydroelectricity is a similar term that refers to the electricity that is produced from this process.Full Answer >
