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 reason why the current does not flow in figure 11.23.
What is because there is a break in the wire?
Why magnets are called dipoles.
What is 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?
What you need to do to make the circuit flow in figure 11.23.
What is push the wire down to it touches the other end of the metal?
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?
How a light "switch" works.
What is when it is off, the circuit is open so no current can flow and when it is on, the circuit is closed to the current flows?
This depends on the percentage of the domains in the material are aligned.
What is the strength of the magnet?
Why the foil strips stayed apart when you touched the balloon to the paper clip in the experiment last week.
What is some of the balloon's extra electrons were able to flow into the paper clip?
The 2 things you need to know to know how much an electric curcuit can do.
What are the current (amps) and the voltage (volts)?
What it is called 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?
Why a light bulb burns out.
What is wear and tear on the filament?
The name of the two sides of a magnet.
What are the north pole and the south pole?
The term that explains why the balloon picked up some electrons when you rubbed it on your hair in the experiment last week.
What is 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 car has several hundred amps running through the ignition 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 type of metal is used to create filaments in light bulbs and can act like a "switch" in a circuit if it breaks.
What is tungsten?
Why permanent magnets exist.
What is because their atoms are aligned so that the movement of their electrons mimics the concerted flow of electricity?
