Electricity
A property that leads to electromagnetic interactions between the particles that make up matter.
What is electric charge?
the rate of flow of electrical charges.
What is electric current?
A complete closed path through which electric charges can flow.
What is electric current.
When you bring two magnets together, they exert a push or pull.
What is magnetic force?
This is able to control the flow of electrons using integrated circuits.
What is an electronic device?
A buildup of electric charge on an object.
What is static electricity?
In this type of current, the way charges move is that they always flow in the same direction.
What is a Direct Current?
The three basic parts to an electric circuit.
What is a energy source, electrical conductor, and a load?
The ends of a magnet.
What is a south end and a north end?
What is an integrated circuit?
A material through which charges can move freely.
What is electrical conductor?
In this type of current, the way charges move is that they repeatedly shift from flowing in one direction to flowing in the reverse direction.
What is a Alternating Current?
In his type of circuit, the current is the same for all of the loads and all three bulbs glow with the same brightness.
What is a series circuit?
An area surrounding a magnet where magnetic forces can be detected.
What is magnetic field?
Analog and digital signals
What are two kinds of signal used by electrons?
A material through which charges can't move easily.
What is electrical insulator?
The amount of work required to move each unit of charge between 2 points.
What is Voltage?
In this type of circuit, the loads are connected side by side, the loads have different currents and each load experiences the same voltage.
What is a parallel circuit?
A material that can be turned into a magnet and can be turned into a permanent magnet when placed in a strong material field.
What is a ferromagnet?
Signals that can change continuously in a given range.
What is an a analog signal?
A special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors.
What is semiconductor?
The opposition to the flow of electric charge.
What is Resistance?
In a series circuit charges follow a single path but in a parallel circuit charges follow multiple paths.
What is the difference between a series circuit and a parallel circuit?
An iron core wrapped with electrical wire.
What is an electromagnetic?
In this type of signal there is a sequence of seperate values.
What is a digital signal?
