Bill Nye the Science Guy Performs a Static Electricity Science Demonstration

# data[].attributes.body
1. Often created by objects that are not good conductors
2. Occurs when different objects' electrons are rubbed together

# data[].attributes.body
Static electricity is the electric charge that has accumulated on an object.

# data[].attributes.body
1. Atoms are grouped together and aligned.
2. Like miniature magnets inside of magnetic items

# data[].attributes.body
Magnetic domain is the section of a magnetic object that contains magnetization in a shared direction.

Introduction to Electrical Resistance by Bambach Wires and Cables

# data[].attributes.body
1. If the resistance remains constant for a certain amount of time, it’s behavior can be predicted using I=V/R
2. Measured in Ohms

# data[].attributes.body
Electrical resistance of a device is the ratio between that device’s voltage and the amount of electricity that flows through it.

# data[].attributes.body
1. Always on the same magnetic field
2. Voltage can be direct or alternating

# data[].attributes.body
Voltage difference is the difference in charge between two points.

# data[].attributes.body
1. This can be proved with magnets
2. All subatomic particles have an electric charge

# data[].attributes.body
The law of electric charge is a scientific law that states that objects with the same electric charge repel each other and objects with different charges attract.

Physics experiments Boiling water using a transformer (science demonstration)

# data[].attributes.body
1. Always electrical energy
2. Consists of a soft iron coil with two coils wound around it

# data[].attributes.body
A transformer is a machine that transfers energy between circuits.

# data[].attributes.body
1. Changes direction in a regular pattern
2. A wall socket has an alternating current

# data[].attributes.body
An alternating current is an electric current that changes its direction of flow.

# data[].attributes.body
1. Through a wire
2. A battery has a direct current

# data[].attributes.body
Direct Current is electricity that only flows in one specific direction.

# data[].attributes.body
1. Turns mechanical energy into electric energy
2. This process can also occur if the current in a wire just changes with time

# data[].attributes.body
Electromagnetic induction is a process using a changing magnetic field that produces electricity in a wire loop.

# data[].attributes.body
A galvanometer is a device that measures electricity using an electromagnet.

# data[].attributes.body
1. Often in a cylindrical form
2. Especially used as a control for a mechanical device

# data[].attributes.body
A solenoid is a coil of wire that performs like a magnet when carrying a current in a way that a movable core is drawn into the coil.

# data[].attributes.body
1. Wrapped around by a coil of insulated wire
2. Contains a soft iron core in the middle

# data[].attributes.body
An electromagnet is a temporary magnet that runs on Electric Current.

# data[].attributes.body
1. Causes the object to change velocity
2. Has both magnitude and direction, so force represents a vector

# data[].attributes.body
Force is the push or pull of an object with mass.

# data[].attributes.body
1. The mechanical energy is also known as motive power
2. These generators provide nearly all the power for electric power grids

# data[].attributes.body
An electric motor is a device that turns mechanical energy into electric energy.

2. Examples of generators include wind turbines, dams, and solar panels

# data[].attributes.body
A generator is a machine that turns one form of energy into another form of energy.

# data[].attributes.body
1. Exists when there is a net flow of electric charge through an area
2. Measured in amperes

# data[].attributes.body
Electric Current is the rate that an electric charge flows past a specific point or region.

# data[].attributes.body
1. Known as Electric Current when it flows
2. Can be used to transfer energy in helpful ways

# data[].attributes.body
Electricity is the presence and flow of electric charge.
