what is currant electricity?
the controlled flow of electrons through a conductor
what does gras stand for?
G- given
R- requiard
A- analies
S- soultion
what is pottential difference?
is the differnece in electric potential energy pur unit charge measured at 2 different points
what is a source?
single dry cell (chemical energy)
how do u calculate for % efficiency?
energy output over energy input x 100%
what is a direct current?
a flow of electrons in one direction through an eletric circut
how do u calulate for cost of operate?
power used x time x cost of electity
what is resistance?
refers to the ability of a conducing substance to slow down the flow of electric currant
what is a control source?
on and off switch
how do u calculate for currant?
charge moving past a point over time
what is alternating currant?
a flow of electrons that alternate in direction an electric circut
why is circut diagram used?
are a pictorial way of showing circuts electricans and enginer draw circut diagrams to help them desgin the actual circut
what does less ressistance rusults in 1/2
less ressitance rusults in more currant energy
what are conducting wires?
a wire in which electorns flow through
how do u calculate for resistance?
potential difference over currant
what is electrical power?
the rate at which electrical energy is produced or consumed
what is electric currants?
is a measure of the rste of electrons flow past a point in a circut.
what does more ressistance results in? 2/2
more ressistance ruslts in less currant
what is a load?
light bulb (energy conversion to heat/light)
how do u calculate for power?
energy over time
what is percent efficiency?
effienecy is the comparsion of energy output of a device with the energy supplied
what is a ammeter?
is a dvice that is used to messure electric currants
what is a circut?
a electricity circut is a continous path in which electrons can flow through
V=?
E=?
Q=?
currant=?
ressistance=?
V= voltage(v)
E= energy (j)
Q= charge (c)
currant= ampears (a)
ressistance= ohms
