3.1
The buildup of electric charge on an object
What is static electricity?
The opposition to the flow of electric charges
What is resistance?
A complete closed path through which electric charges can flow
What is an electric circuit?
Any material that attracts iron or objects made of iron
What is a magnet?
able to control the flow of electrons using integrated circuits
What are electronic devices?
a material through which charges move freely
What is an electrical conductor?
What is Voltage?
This converts a type of energy to another(ex: chemical energy to electrical energy)
What is an energy source?
When 2 magnets are brought together(the push or pull)
What is a magnetic force?
A single tiny chip of specially treated silicon containing many circuit parts, and carry out instructions or programs by current
What is an integrated circuit?
A material through which charges cannot move easily
What is an electrical insulator?
The rate of flow of electric charges
What is electric current?
What is a load?
the ends of a magnet
What are magnetic poles?
Signals that change continuously in a given range.
What are analog signals?
A special class of materials that conduct charge better than insulators but worse than conductors.
What is a semi-conductor?
current times voltage
What is power?
A circuit in which all parts are connected in a row that forms one path for the electric charges to follow
What is a series circuit?
groups of atoms where the south and north poles line up and make a strong magnetic force
What is a domain?
What are digital signals?
A property that leads to electromagnetic interactions between particles
What is electric charge?
What is voltage?
A circuit in which electric charges have more than 1 path that they can follow
What is a parallel circuit?
A material that can be turned into a magnet
What is a ferromagnet?
any electronic device that performs tasks by following instructions given to it
What is a computer?
