a circuit which has two paths, which conect later in the curcuit
a circuit in which there is more than one component, not encluding switch and voltmeter ect
would the lights be more dim in a series circuit, and if so why?
yes they would, because the energy is shared across lots of different components
yes, because the lights are evil and are sucking the energy out.
no, it all stays the same
no, they all burn brighter because all the bulbs make friends and are made brighter by the power of frendship.
what is a parallel circuit?

A parallel circuit comprises branches so that the current divides and only part of it flows through any branch.
a curcuit with two different paths, one of them with a switch, the other one empty
frendship is magic :)
a (a) circuit has junctions
-------- can be used to controll the current and break or start the flow of energy
(a)
