Electricity Chapter 11

• a closed path which electrons that are powered by an energy source can flow.
• 

• a source of energy that generates current by chemical reactions involving two different metals or metal compounds by separated by a conducting solution.
• 

• a connection of two or more cells
• 

one of two metal terminals in a cell or battery

• a solution or paste that conducts charge
• i.e dry cells have a paste electrolyte

• A cell that contains an electrolyte made out of paste
• 

• a cell that contains a liquid electrolyte
• i.e. car battery

• a cell that can only be used once
• i.e. AAA battery, AA battery

• A cell that can be recharged
• i.e. car batteries, rechargeable batteries

a cell that generates electricity through chemical reactions that is stored outside the cell

• a cell that converts sunlight into electrical energy
• 

a position on a cell that must be connected to other components to form a circuit

• a control device that  can complete a circuit to which it is connected
• 

• a circuit that contains a gap or break
• 

A measure of the number of charged particles that pass a point in an electric fieldMeasured by an ammeterUnit is Amperes or Amps

the quantity of charge that is equal to the charge of 6.25 x 10^18

• It is the unit of electric current 
• equivalent to 1 coulomb per second

• The property if a substance that hinders electric current and converts electrical energy to other forms of energy
• i.e incandescent light bulbs have a lot of heat out because of resistance.

a device used in an electric circuit to decrease the current through a component by a specific amount.

• 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.

The difference between the electric potential energy per unit of charge at two points on a circuit

the unit for potential difference equivalent to one joule per coulomb.

• a diagram that uses standard symbols that represent the components in an electric circuit and their connections
• 

• a circuit in which there is only one path along which electrons can flow.
• 

• a circuit in which there is more that one path along which electrons can flow
• 

• The ratio of potential difference to current is a constant called resistance.
• 

the unit for resistance and is equivalent to one volt per ampere (v/a)

a conductor in which electrical charge can flow with no resistance

Something that doesn't follow ohm's law
