# Electricity Chapter 11

 Electric circuit a closed path which electrons that are powered by an energy source can flow. Voltaic cell a source of energy that generates current by chemical reactions involving two different metals or metal compounds by separated by a conducting solution. Battery a connection of two or more cells Electrode one of two metal terminals in a cell or battery Electrolyte a solution or paste that conducts chargei.e dry cells have a paste electrolyte Dry cell A cell that contains an electrolyte made out of paste Wet cell a cell that contains a liquid electrolytei.e. car battery Primary cell a cell that can only be used oncei.e. AAA battery, AA battery Secondary cell A cell that can be rechargedi.e. car batteries, rechargeable batteries Fuel cell a cell that generates electricity through chemical reactions that is stored outside the cell Solar cell a cell that converts sunlight into electrical energy Terminal a position on a cell that must be connected to other components to form a circuit Switch a control device that  can complete a circuit to which it is connected Open circuit a circuit that contains a gap or break Electric current A measure of the number of charged particles that pass a point in an electric fieldMeasured by an ammeterUnit is Amperes or Amps Coulomb (C) the quantity of charge that is equal to the charge of 6.25 x 10^18 Ampere (A) It is the unit of electric current equivalent to 1 coulomb per second Electrical resistance The property if a substance that hinders electric current and converts electrical energy to other forms of energyi.e incandescent light bulbs have a lot of heat out because of resistance. Resistor a device used in an electric circuit to decrease the current through a component by a specific amount. Load a resistor or any device that transforms electrical energy into heat, motion, sound, or light.i.e. a light bulb would be a load that transforms electrical energy to light and heat energy. Potential difference (voltage) The difference between the electric potential energy per unit of charge at two points on a circuit Volt the unit for potential difference equivalent to one joule per coulomb. Circuit diagram a diagram that uses standard symbols that represent the components in an electric circuit and their connections Series circuit a circuit in which there is only one path along which electrons can flow. Parallel circuit a circuit in which there is more that one path along which electrons can flow Ohm’s law The ratio of potential difference to current is a constant called resistance. Ohm (Ω) the unit for resistance and is equivalent to one volt per ampere (v/a) Superconductor a conductor in which electrical charge can flow with no resistance Non-ohmic Something that doesn't follow ohm's law Loads in Series Loads in Parallel AuthorHuckKim ID313846 Card SetElectricity Chapter 11 DescriptionMs. Day's Gr.9 science class cue cards Updated2016-01-08T00:22:11Z Show Answers
