any unbroken loop of electrical components that forms a continuous conducting path.
the movement of electrons
materials and conditions needed for bulb to light
batteries, wires, battery holder, socket, circuit
which way does electricity move?
positive to negative
true or false metal substances are usually good conductors? evidence?
true or false a compass can be used to determine the exact direction that charge flows in a circuit? evidence?
False we don't know which way it goes. it shows relative direction
true or false a battery determines the direction of flow of charge in the circuit. Evidence.
true because it goes positive to negative.
true or false Charge moves out of the end of the battery into the loop. evidence
false the battery only pushes the electrons
what happens if there is a break in the loop?
the lights don't turn on.
why does it appear that the lights go on at the same time?
the electrons move like a conveyer belt. when the loop is connected the lights are on but when the loop is broken then the lights are off.
