electricity last topic letssssssssssssssss GOOOOOOOOO Flashcards
branches def
part of a parellel cuircut where the current divides
conected in parelell
components that attached acrosss each other so that the terminals of one compnent are conected to the terminales of the other
conected end to end
only one path for curent to flow
conected in series
components that are joined so that all the curent flowing out of one component flows into the next
parallel circut
cuircut where curent can flow more than one route
the current through the cell is equal to the total of the current in all the branches
components in the same curciut be switeched of independently
if one branch break others unefected
resitince
in an electrical circuit anything that tends to slow the flow of the current
battery
two or more electrical cells conected in a series
mains
the power suply from a wall socket:
220 - 240 v in most contreies or 110 - 120 v
rating
the maximum current or voltage that can be saftly used without damegeing a component
supply
to provide somthing : a power suply provides voltage to drive current in a circuit
voltage
a quantity that is related to either the energy supplied by a power supply or the enerny changed by a component
voltmeter
a meter that is conected in parrellel with component in order to mesaure the voltage on either side of that component
volts
the unit of voltage
related to energy but it is
not energy
what is the avrage energy supplied by cell and battery
most cells = 1.5 v
most batteries = 6v, 9v or 12v
adding cells to a parellel cucuit will
-increase the voltage
-increase voltage acrosss each branch
-increase the current through the cell
-increases the current through each branch
filament
the high resitance wire used in some lamps and in some radiant heaters
