Electric Charge and Static Electricity
A property that leads to electromagnetic interactions between the particles that make up matter.
What is Electric Charge?
Electrical resistance, or ohms, are influenced by what three factors
What are material composition, thickness and temperature?
Most outdoor lights are wired this way so that if one light burns out the rest will continue to shine.
What is a parallel circuit?
A region around a magnet in which you can measure magnetic forces.
What is a magnetic field?
A device in which a magnet moves in a coil of wire to produce electricity?
What is a generator?
The rapid or gradual loss of static charges from an object.
What is electric discharge?
This type of materials have the most resistance to an electric current.
What are insulators?
When a light bulb fails to light there might be a break in the path of the electricity creating this type of circuit.
What is an open circuit?
An area of material where north and south poles of atoms line up.
What is a domain?
An electromagnet is made by wrapping a coil of wire called this around an iron core.
What is a soleniod?
These are the three parts of an atom and their charges.
What are Proton (+), Neutron (neutral) and electron (-)
The amount of work required to move each unit of electric charge between two points.
What is voltage?
You should never fly a kite during a lightning storm because lightning usually strikes items with this relation to the ground.
What is high above the ground?
The magnetic north and south poles of this enormous magnet are not opposite of their geographical position.
What is the Earth's magnet?
This is a tiny sheet of silicon containing an entire circuit with many different components.
What is an integrated circuit?
These are materials that allow charges to flow through them freely.
What are conductors?
The rate of flow of electric charges, measured in amperes.
What is electric current?
This type of circuit creates an open circuit to the rest of the loads when one bulb burns out.
What is a series circuit?
This type of magnet is not easily magnetized but retains its magnetic properties for a long time.
What is a permanent magnet?
This part of a computer allows it to run programs and decode inputs.
What is a CPU (central processing unit)?
These are the three ways in which an object can become electrically charges.
What are by friction, induction and contact?
Unlike the type of current found in batteries, this type of current flows to the appliances in our homes.
What is alternating current (AC)?
This is a special kind of circuit breaker most often found in bathrooms and kitchens.
What is a GFCI (ground fault circuit interrupter)
The alignment of atoms within a material and the alignment of the domains they create would give the material this property.
What is magnetism?
Unlike signals that change continuously in a given range (like a dimmer switch), these signals are a sequence of separate values (like an on/off switch).
What are digital signals?
