open circuit
In a experiment, we had circuits that wouldn't work. What is a circuit that has a gap or break in it.
100
parallel circuit
What is a circuit that has two or more paths to follow?
200
metals: copper, silver, aluminum
What are material examples of conductors?
200
closed
What is the circuit called when the electric current can flow?
200
positive charges and negative charges
What are two kinds of charges?
200
static electricity
We had balloons that repelled or attracted to each other because we rubbed them with materials. What is this called?
200
series circuit
What is the circuit that has only one pathway for an electric current to follow?
300
negative charges
Which of the charges move from one object to another object?
300
a power source (battery), insulated wire, iron bar or nail
What are the the three things that you must have to create an electromagnet?
300
Neutral
What is having a balance or the same amount of positive and negative charges.
300
series circuit
What is the circuit that has only one path for a current to follow?
300
electric circuit
What is a continuous pathway that can carry an electric current?
400
open circuit
What is wrong with a circuit if there is no connection with the battery? It is considered to be what?
400
electromagnet
What is a temporary magnet that is make up of a coil of wire wrapped around an iron core?
400
a negatively charged object
What is an object that has more negative charges than positive charges?
400
parallel circuit
What is the circuit that allows other bulbs to light up even if one of the bulbs does not work?
500
Current electricity is easily controlled.
What is the reason that current electricity is more useful than static electricity?
500
conductors
What is a material that allows electricity (negative charges) to flow through it easily?
500
resistence
What is the measure of how much a material opposes the flow of current?
500
power source (battery), wire, and bulb
What three things that you needed to make the light bulbs work?
500
A parallel circuit has two or more paths for an electric current to follow. A series circuit has only one path for an electric current to follow. When a series circuit has a break or gap, the circuit doesn't work. When a parallel circuit has a break or gap, the circuit continues to work.
What are two differences between a parallel circuit and a series circuit?
