the law that states that like charges repel and opposite charges attract
What is law of electric charges?
100
The center of an atom
What is the nucleus
100
a device that can tell if something is charged by using two metal leaves
What is an electroscope
100
a lightning rod on top of a building should be this, since it is connected by a wire to the ground
What is grounded
100
a switch that automatically opens a switch if the current is too high
What is a circuit breaker
200
the particle inside an atom that is negatively charged
What is an electron
200
the particle inside of an atom that has no charge
What is a neutron
200
Rubber keeps electrons from moving freely because it has this property
What is electrical insulator
200
In electricity terms, this is the specific meaning of DC
What is direct current
300
charging that occurs when electrons are wiped from one object onto another
What is charging by friction
300
The positively charged particle inside of an atom
What is a proton
300
copper, aluminum, and mercury have this property in common, because they allow electrons to move freely
What is electrical conductor
300
a type of circuit in which all the parts connect in a single loop with a single path for the charges to follow
What is a series circuit
300
this type of cell converts light energy into electrical energy
What is a photocell
400
charging that occurs when electrons move from one object to another by direct contact or spark
What is charging by conduction
400
This law states that objects with the same charge repel one another and with opposite charges attract one another.
What is the law of electric charges
400
a type of electricity that stays on an object and does not move
What is static electricity
400
this type of circuit carries loads connected side by side in which current flows through more than just one single path
What is a parallel circuit
400
the opposition to the flow of electric charge
What is resistance
500
charging that occurs when charges in an uncharged metal object change without direct contact with a charged object
What is induction
500
the region around a charged object in which an electric force is exerted on another charged object
What is an electric field
500
striking from the sky, this usually strikes the highest point in a charged area
What is lightning
500
This safety measure is a thin strip of metal placed in the wiring at the beginning of a circuit. If the current is too high, the strip melts and breaks to stop the flow of the charge.
