Electricity | The flow of electrons through a conductor. |
Law of Electric Charges | Charges repel and opposite charges attract. |
Static Electricity | An electrical charge that is built up in one place and it is static ( not moving). |
Electric Discharge | The loss of static electricity as charges move off an object. |
Conduction | Can transfer the electrons from one object to another by direct contact. |
Electroscope | This is used to detect charge. |
Cell | Divice that produces an electric current |
Photocell | Converts Solar Energy to electrical energy |
Current | Measure of the rate at which an electron passes a point each second |
Voltage | electromotive force or potential difference expressed in volts. |
Resistance | Opposition to the flow of electrons |
AC | Altering Current |
DC | Direct current |
Circuit | A path that the charges follow |
Series Circuit | Conected in a single loop. |
Electric Power | the product of voltage and current |
Magnetic Field | the lines of force surrounding a permanent magnet |
Magnetic Force | The force exerted between magnetic poles |
Electromagnetism | Magnetism produced by electric charge in motion |
Generator | machine that converts one form of energy into another |
Transformer | A device used to transfer electric energy from one circuit to another |
Induction | The charging of an isolated conducting object by momentarily grounding it while a charged body is nearby. |
Parallel Crcuit | a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit |
Load | a device that receives power. |
