Understanding electrical current
100
by rubbing them
How do you charge an object?
100
positive (+) and negative (-)
what are the two types of electrical charge?
100
metals
What are good conductors of electricity?
100
Metals, but not plastic.
What can an electric current flow through?
200
It can produce a force of attraction or repulsion.
What can an electrically charge object produce?
200
positive and positive- repel negative and negative- repel positive and negative- attract
What two forces attract and what forces repel?
200
a complete circuit of metal in which the current can flow and a cell
What do you need to make an electric current?
200
it is when the resistor is arranged in chain
what is a series circuit?

You can rub a balloon on a cloth and it will charge it with static electricity.
What is an experiment you can do to show static electricity?
300
coulombmeter
What can you use to find an object charge?
300
Because if everyone uses the same symbols they can understand each other's diagrams.
Why are there circuit symbols?
400
electrical attraction
What is an example of a force?
