Charge!
Charging an object by rubbing two items together where one transfers electrons to the other.
What is Charging by Friction?
The amount of charge that travels past a fixed point in an electric circuit each second.
What is electrical current?
While he is one of our Founding Fathers, he is also a very respected scientist.
Who is Benjamin Franklin?
The name for a circuit in which electricity cannot flow.
What is an open circuit?
This is why magnets are called dipoles.
What is because magnet poles always come in pairs: one north and one south?
Charging an object without direct contact between the object and a charge.
What is Charging by Induction?
In order to get electrical charges moving, you need this.
What is something that uses electromagnetic force?
Current that flows from the positive side of the battery to the negative side.
What is Conventional Current?
This is the type of circuit in which all bulbs would stop working if one bulb burned out.
What is a series circuit?
A cluster of many atoms that have their magnetic fields aligned and so act as a magnet.
What is a magnet domain?
Charging an object by allowing it to come into contact with an object that already has an electrical charge.
What is Charging by Conduction?
A simple household item that uses electromagnetic force to get electrical charges moving.
What is a battery?
The type of energy that is energy of movement.
What is kinetic energy?
This is what happens when one bulb goes out on a parallel circuit.
What is no other bulbs would go out?
This depends on the percentage of the domains in the material are aligned.
What is the strength of the magnet?
When an object loses electrons, it becomes this.
What is positively charged?
What are the current (amps) and the voltage (volts)?
This occurs when some of the kinetic energy has been converted and there is less energy available to move electrons through the wire, which means the current will be reduced.
What is resistance?
Cooktop burners are made of a specific metal that produces a lot of ___________, but not a lot of _________.
What is heat and light?
The name of the two sides of a magnet.
What are the north pole and the south pole?
Charging an object by rubbing two items together is called this.
What is charging by friction?
The reason why touching and exposed battery cable on a car that is being started can kill you while a small electrical toy running on a 9-volt battery will not.
What is the higher level of amps running through the circuit?
The 2 reasons why metal wire is usually coated with plastic or rubber.
What is the coating around the wire helps to keep the metal's valence electrons where they need to be and to protect you from getting a shock when working with a circuit?
This is the part of a light bulb which indicates when the circuit is closed or open.
What is the filament?
These are three common uses for magnets.
