Chapter 11 Glossary Terms
A closed path along which electrons that are powered by an energy source can flow.
eg. battery, generator, motor
A source of energy that generates an electric current by chemical reactions involving two different metals or metal compounds separated by a solution that is a conductor.
A connection of 2 or more cells
1 cell = 1.5 V
One of two metal terminals in a cell
a liquid or gel which contains ions and can be decomposed by electrolysis, e.g. that present in a battery.
an electric cell in which the electrolyte is absorbed in a solid to form a paste, preventing spillage.
a primary electric cell in which the electrolyte is a liquid.
an electric cell that produces current by an irreversible chemical reaction.
storage cell; a cell that can be recharged
a cell producing an electric current direct from a chemical reaction.
a device converting solar radiation into electricity.
a point of connection for closing an electric circuit.
a device for making and breaking the connection in an electric circuit.
consisting of or containing an open electric circuit.
a flow of electricity through a conductor
the SI unit of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.
a unit of electric current equal to a flow of one coulomb per second.
a material's opposition to the flow of electric current; measured in ohms
a device having resistance to the passage of an electric current.
A device or the resistance of a device to which power is delivered.
Potential difference (voltage)
the difference of electrical potential between two points.
the unit for potential difference equivalent to one joule
a simplified conventional graphical representation of an electrical circuit.
a circuit having its parts connected serially
a closed circuit in which the current divides into two or more paths before recombining to complete the circuit
a law stating that electric current is proportional to voltage and inversely proportional to resistance.
the SI unit of electrical resistance, transmitting a current of one ampere when subjected to a potential difference of one volt.
A conductor with no electrical resistance
resistors have changing ratios, and are defined by their instantaneous resistance
