The type of circuit you have to have to make a light bulb light up
open and closes a circuit
has more than one path for the electricity to travel on
all other bulbs will stay lit if one goes out
changes electricity into light energy
allows electricity to flow through it
a iron nail is this
stops the flow of electricity
a plastic comb is this
the bulb will stay lit if this kind of object is added to the circuit
a flashlight turns electrical energy into what
an oven turns electrical energy into what
an example of electrical energy into sound energy
three types of energy that can be transformed from electrical energy
an example of electrical energy into heat energy
names of the poles of a magnet
these poles attract
these poles repel
an object a magnet will pick up
A magnets pull or attraction is strongest here
A stronger battery will make an electromagnet stronger or weaker
True or False: The neatness of the coils affect the strength of the electromagnet
