Science
| Term | Definition |
|---|---|
| a continuous, unbroken path through which electricity can flow | circuit |
| a material through which electricity flows easily | conductor |
| a conductor that can be moved so that it either bridges or doesn't bridge a circuit | switch |
| a situation caused by electricity taking an unexpected path | short circuit |
| does not allow electricity to flow through it | insulator |
| reduces the flow of electrons | resistor |
| a circuit that has only one path for electricity to travel | series circuit |
| A circuit that has only two or more paths through which electricity can travel | parallel circuit |
| the measurement of the amount of push, or force, in a circuit | volt |
| a measurement of the amount of power, or how fast work is done | watt |
| the amount of current that flows through a point of a circuit in a second | ampere |
| device consisting of two metals and an electrolyte that produces an electric current | electric cell |
| liquid or paste that conducts electricity | electrolyte |
| an object that is able to attract iron | magnet |
| the area around a magnet where the force the magnet can act | magnetic field |
| a temporary magnet formed when an electric current flows through a coil of wire | electromagnet |
| magnetic levitation | maglev |
| electric current that carries information | electrical cell |
| uses open and closed circuits to communicate the numbers 0 and 1 | binary number system |
| very small circuit will all components in a single circuit | integrated circuit |
| can work as a conductor or as an insulator | semiconductor |
| difference between current electricity and static electricity | Static electricity is the buildup of electrical charges on the surface of an object and current electricity is the continuous flow of electrons around a circuit |
| How does a battery work? | a chemical reaction between two metals and an electrolyte produces electrons that move from the negative terminal and along a wire to the positive terminal to complete the circuit and produce an electrical current |
| Relationship between electricity and magnetism | the flow of electricity can produce a magnet moving around a wire that can produce electricity |
| Discovered that a wire has a magnetic field | Contributions of Hans Christian Oersted |
| discovered electromagnet and the generator | Contributions of Joseph Henry and Michael Faraday |
| Discovered that adding a metal core to a coil of wire increases the magnetism to make an electromagnet | Contributions of William Sturgeon |
| How does an electromagnet work? | A coil of wire with a coil of wire attached to an electrical source and wrapped around a metal core |
| How does a generator work? | The movement of a magnet within a coil of wire or of wire within a magnet causes an electrical current |
| differences between an electrical device and electronic device | an electronic devise that uses electricity to communicate information and an electrical devise is an electric current that carries information |
| parts of a computer | CPU, RAM, ROM |
