PHYSICAL SCIENCE MODULE 6 VOCABULARY
Question | Answer |
---|---|
the accumulation of excess electric charge on an object | static electricity |
states that charge can be transferred from one object to another, but it cannot be created or destroyed | law of conservation of charge |
a region surrounding every electric charge in which a force of attraction or repulsion, is exerted on other electric charges | electric field |
material through which electrons can move easily | conductor |
material in which electrons and thermal energy are not able to move easily | insulator |
the transferring of electrical charge between objects by touching or rubbing | charging by contact |
the rearranging of electrons on a neutral object caused by bringing a charged object close to it | charging by induction |
a device consisting of two leaves of metallic foil used to detect electric charge | electroscope |
the net movement of electric charges in a single direction | electric current |
related to the force that causes electric charges to flow | voltage difference |
a closed path that electric current follows | electric circuit |
tendency for a material to oppose electron flow and to convert electrical energy into other forms of energy, such as thermal, energy and light | resistance |
states that the currents in a circuit equals the voltage difference divided by the resistance | Ohm's Law |
circuit in which electric current has only one path to follow | series circuit |
circuit in which electric current has more than one path to follow | parallel circuit |
rate at which electrical energy is converted to another form of energy | electrical power |
