Science Words about electricity
Question | Answer |
---|---|
circuit | a special type of network, one that has a closed loop giving a return path for the current |
conductor | a material allowing the flow of electrical charge |
electric current | a flow of electric charge through a conductive medium |
electric discharge | describes any flow of electric charge through a gas, liquid or solid |
electric field | the region of space surrounding electrically charged particles and time-varying magnetic fields. |
electric force | law of physics describing the electrostatic interaction between electrically charged particles |
electric power | the rate at which electric energy is transferred by an electric circuit |
insulator | a substance that resists electric current |
ion | an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge |
ohm's law | the current through a conductor between two points is directly proportional to the potential difference across the two points |
paralled circuit | Components of an electrical circuit or electronic circuit can be connected in many different ways |
resistance | the opposition to the passage of an electric current through that element; the inverse quantity is electrical conductance, the ease at which an electric current passes. |
series circuit | Components connected in parallel are connected so the same voltage is applied to each component. |
static charge | an excess of electric charge trapped on the surface of an object |
voltage | the electric potential difference between two points — or the difference in electric potential energy of a unit test charge transported between two points |
