Static Electricity & Electrostatic Series
What is static electricity?
This type of electricity is caused by a buildup of electric charges on a surface.
What is a photocopier?
Static makes the powder stick to the paper.
What is a battery?
A battery is a device that gives energy to a circuit so electricity can flow.
What is a circuit?
A circuit is a complete loop that lets electricity flow.
Why is water dangerous near electricity?
Water is dangerous because it can carry electricity and cause shocks.
What is rubber?
This material becomes negatively charged when rubbed with wool, according to the electrostatic series.
What is opposite charges attract?
The balloon has one charge and the wall has the opposite.
What are terminals?
Terminals are the positive and negative ends of a battery.
What is a series circuit?
A series circuit has only one path for electricity to follow.
What is a fuse?
A fuse is a safety device that stops electricity if there is too much current.
What is electrons transferring and causing like charges to repel?
This is the reason your hair may stand up when you take off a wool hat.
Why do clothes sometimes stick together when they come out of the dryer?
Because they rub together and build up static charges that attract each other.
What is a rechargeable battery?
A rechargeable battery is a battery that can be used again after charging.
What is resistance?
Resistance is how much a material slows down the flow of electricity.
Why should you never touch electrical devices with wet hands?
Because water lets electricity pass through your body and can shock you.
What is grounding?
This method allows excess static charge to flow safely into the Earth.
Why do they stop static in electronics factories?
Static control is important because static electricity can damage small electronic parts.
How does a dry cell battery work?
A dry cell battery works by using a chemical reaction to make electrons move.
What happens when more bulbs are added to a series circuit?
The bulbs get dimmer because they share the same energy.
How can bad wiring cause fires?
If wires get too hot from too much current, they can start a fire.
What is plastic becomes negatively charged because it holds electrons more tightly than silk?
Plastic takes electrons because it holds them more strongly.
How does electrostatic painting work?
The paint and object have opposite charges, so the paint spreads out and sticks evenly.
What is the difference between a dry cell and a rechargeable battery?
A dry cell is used once, but a rechargeable battery can be used many times.
What is Ohm’s Law?
Ohm’s Law: Voltage = Current × Resistance.
What is the difference between a fuse and a circuit breaker?
A fuse must be replaced after it breaks, but a circuit breaker can be turned back on.
