Catégorie : Physics chapter 22 current electricity

a flow of electric charge or electric current, equal to one coulomb per second (SI unit for current)

a flow of charged particles -the movement of electric charge -exists whenever there is a net movement of electric charge through a medium – current is the rate at which electric charges…

-a closed loop or pathway that allows electric charges to flow

is the difference in electrical potential between 2 points in a circuit -its the push or pressure behind the current flow through a circuit, and is measured in volts

I = Q/t

high voltage points to low voltage points

a material with zero resistance that can conduct electricity without the loss of energy

positive, negative, or combination of the two

– a device made up of several galvanic cells connected together that converts chemical energy to electric energy

a type of connection in which there are several current paths; its total current is equal to the sum of the currents in the individual branches, and if any branch is opened,…
