Glossary terms chapter 11

A closed path along which electrons that are powered by an energy source can flow

A source of energy that generates an electrical current by chemical reactions involving two different metals or metal compounds separated by a solution that is a conductor.

A connection of two or more cells

One of two metal terminals in a cell or battery

A solution or paste that conducts charge

A cell that contains an electrolyte that is a paste

• A cell that contains a liquid electrolyte
• e.g salt solution in Volta's pile

A cell that can be used only once

A cell that can be recharged

• A cell that generates electricity through the chemical reactions of fuel that that is stored outside the cell 
• e.g fuel cell busses

A cell that converts sunlight into electrical energy

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

A control device that can complete or break the circuit to which it is connected

A circuit that contains a gap or break

The rate of movement of electric charge

• The quantity of charge that is equal to the charge of 6.25×10(to the power of 18)
• (sorry but superscript does not work)

The unit of electric current,  equivalent to one coulomb per second

The property of a substance that hinders electric current and converts electrical energy to other forms of energy 

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

A resistor or any other device that transforms electrical energy into heat, motion, sound, or light

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

The unit for potential difference,  equivalent to one joule (J) per coulomb (C)

A diagram that uses standard symbols to 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 than one path along which electrons can flow

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

R=V/I

The unit for resistance,  equivalent to one volt per ampere (V/A)

A material through which electric charge can flow with no resistance.
