T/F
is there only one electricity current?
False there is two current electricity
list 3 sourues of voltage
friction , magnnestiesm , chemicals
idenifty the parts of electric circuit
Engery source , enegry reciver , energy pathway
is lighting static electricity?
Yes , just a bigger verison of small burst of electricity
explain how voltage is related to electric current
current is the effect caused by voltage
list 3 tips to reduce the risk of injury or fire from electricity
dont run out of cords,do not over load outlets , and change the batteires
Do you need a swicth for your battiers to work?
Not all the time, you have some wires work without
idenify 3 properties that affect the resistance of a given material
width , lenght , temputure
what variables determine the amount of electrical enegry an appilance uses
power and time
is voltage formlua amps
Yes
what is electirc current?
is the movement of particles , starting at the movement when a extrenal voltage is appiled to one at the end of an conductor
ideifney an electri safey feature
circuit breakers
do the swicthes always increase or derease
ture they can do both so there wires are both good for the swicth
what is the difference between direct and alternating current
the current directions and how they have neagtive and postive charges
explain how a short circuit works
there is a current that finds a way to pass the applicance on a path and has no lines for no resistances
