Electricity 5.4
| Question | Answer |
|---|---|
| Q: What is electricity? | A: Electricity is a form of energy resulting from the flow of electric charge |
| Q: What are protons and electrons? | A: Protons are positively charged particles, while electrons are negatively charged particles that move around an atom's nucleus. |
| Q: What is static electricity? | A: Static electricity is the buildup of electric charge on the surface of an object, which can cause a spark or shock when it moves |
| Q: What is a circuit? | A: A circuit is a closed path through which electricity flows. |
| Q: What are conductors? Give an example. | A: Conductors are materials that allow electricity to flow through them easily. Example: Copper. |
| Q: What are insulators? Give an example. | A: Insulators are materials that do not allow electricity to flow through them easily. Example: Rubber. |
| Q: What is a series circuit? | A: A series circuit has only one path for electricity to flow. |
| Q: What is a parallel circuit? | A: A parallel circuit has multiple paths for electricity to flow. |
| Q: What is an electric current? | A: Electric current is the flow of electric charge through a conductor. |
| Q: What is voltage? | A: Voltage is the force that pushes electric charges through a conductor. |
| Q: What is a battery, and how does it work? | A: A battery is a device that converts chemical energy into electrical energy to provide a voltage. |
| Q: How do switches work in a circuit? | A: Switches control the flow of electricity by opening (stopping the flow) or closing (allowing the flow) a circuit. |
| Q: Name two types of energy that electricity can be converted into. | A: Electricity can be converted into light energy and thermal (heat) energy. |
| Q: What is electromagnetism? | A: Electromagnetism is the interaction of electric currents or fields and magnetic fields. |
| Q: What is a magnet, and how is it related to electricity? | A: A magnet is an object that produces a magnetic field. Electricity can create magnetic fields, which is the basis of electromagnets. |
| Electricity | A form of energy resulting from the movement of charged particles, like electrons, through a conductor. |
| Atom | The basic unit of matter, consisting of a nucleus surrounded by electrons. |
| Proton | A positively charged particle found in the nucleus of an atom. |
| Electron | A negatively charged particle that orbits the nucleus of an atom and can move between atoms, creating electric current. |
| Static Electricity | The buildup of electric charge on an object’s surface, which can result in a sudden release of energy, like a spark. |
| The flow of electric charge through a conductor, such as a wire. | |
| Circuit | A closed loop or pathway that allows electric current to flow. |
| Conductor | A material, often metal, that allows electric current to flow easily. Example: copper. |
| Insulator | A material that does not allow electric current to flow easily, used to protect against electric shock. Example: rubber. |
| Series Circuit | A type of circuit with only one path for electricity to flow. If one part of the circuit is broken, the current stops. |
| Parallel Circuit | A type of circuit with multiple paths for electricity to flow. If one path is broken, current can still flow through other paths. |
| Electric Current | The continuous flow of electric charge, measured in amperes. |
| Voltage | The force or pressure that pushes electric current through a conductor, measured in volts. |
| Battery | A device that stores chemical energy and converts it into electrical energy to provide voltage. |
| Switch | A device in a circuit that can open or close the circuit, controlling the flow of electricity. |
| Electromagnet | A magnet created by passing electric current through a coil of wire wrapped around an iron core, which can be turned on and off. |
| Magnet | An object that produces a magnetic field and attracts ferromagnetic materials like iron. |
| Magnetic Field | The area around a magnet where magnetic forces are exerted. |
| Energy Conversion | The process of changing energy from one form to another, such as electrical energy to light or heat. |
