Static Electricity
Definitions
True Or False
100
What are the the two types of circuits?
Series circuits and parallel circuits.
100
To make static electricity, you _ two things together.
rub
100
Is static electricity easy to make/generate/find?
Yes, it is incredibly easy. There are tons of easy ways to generate/make/find static electricity (rubbing a balloon on your hair, dragging rubber soled shoes on a carpet, etc.).
100
What is the definition of energy?
Energy is the ability to do work.
100
A series circuit is the same as a parallel circuit.
False. Series circuits and parallel circuits have different properties, different advantages and disadvantages, and are just overall different.
200
Is water positively charged, neutral, or negatively charged?
Water is neutral.
200
When two things are both positively charged, they _ each other.
repel
200
What are some examples of ways to generate static electricity?
Some ways to generate static electricity are: - rubbing a balloon on your hair -dragging rubber soled shoes across a carpet -t.v. generates static electricity
200
What is the definition of current electricity?
An ELECTRIC CURRENT (current electricity) is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire.
200
If an object possesses/has more protons than electrons, it has a neutral charge.
If an object possesses/has more protons than electrons, it has a neutral charge.
300
What are some advantages and disadvantages of parallel circuits and series circuits?
Parallel Series ADVANTAGES: ADVANTAGES: - if one bulb - it uses less wires turns off the - easier to build/make others still DISADVANTAGES stay on - if one bulb turns off/ is disconnected/ - houses breaks, the others all turn off as well use parallel circuits DISADVANTAGES: - it uses more wires (takes up more space)
300
Static electricity is a form of energy caused by the _.
movement of electrons
300
What happens when you rub a balloon on your hair? Why?
Your hair sticks to the balloon, because the balloon steals electrons from your hair. This causes your hair to have a positive charge and the balloon to have a negative charge. Opposites attract, so your hair pulls/attracts to the balloon.
300
What is the definition of an open circuit and a closed circuit?
An open circuit is a broken circuit where the electrons cannot continuously flow. A closed circuit is a complete circuit that allows the electrons to flow continuously from the power source and back.
300
An atom is made up of two particles.
False. An atom is made up of THREE particles (electrons, protons, and neutrons).
400
What is it called when an atom does not give off any electrical charge?
It is called an ion, or a balanced atom.
400
A form of energy caused by movement of electrons is called _.
electron-static charge.
400
How is static electricity generated? Give lots of detail.
When you rub two things together, one steals the electrons from another. For example, when you rub a balloon on your hair, the balloon steals the electrons from your hair, so your hair sticks to the balloon.
400
What is the definition of renewable and non-renewable energy?
Renewable energy is energy from a source that can re-make the energy, so it never runs out (wind=wind turbines, sun=solar panels, etc.). Non-Renewable energy is energy from a source that cannot be replaced, so it can run out of energy.
400
An atom has nucleus in it.
True. Over 99.94 of an atom's mass is nucleus.
500
What are some examples of conductors and insulators?
Conductors Insulators - silver - rubber - copper - paper - aluminum - plastic - nickels - oil - salt water - popsicle sticks - most metal
500
An atom is similar to the solar system because in the center of the atom is the _ and in the center of the solar system is the _.
1= nucleus 2= sun.
500
Why do you feel and see a spark when you touch somebody after you drag rubber soled shoes on a carpet?
You see and feel a spark when you touch somebody after you drag rubber soled shoes on a carpet because when you drag rubber soled shoes on a carpet you collect/steal electrons from the carpet. The electrons spread all over you as far apart from each other as they can get. Then, when you touch somebody, all the electrons jump onto them, trying to get away from each other even more. The jump so fast that you can see them and feel them jumping/traveling into/onto that other person. Now they have a negative charge.
500
What is the definition of a switch?
A device that interrupts the flow of electricity in a circuit, as in a light switch.
500
In order for current electricity to flow, electrons need a good conductor to allow them to move.
True. If current electricity doesn't have a good conductor, how is it ever going to flow?
