Magnets
A tool used to find the Earth’s north pole
What is a compass?
A material that allows electricity to flow through it easily.
What is a conductor?
a material that does not allow heat or electrons to move through it easily
What is an insulator?
S=d/t
What is speed?
The path along which negative charges can flow
what is an electrical circuit?
Repel
What is the act of one object being pushed away from another object?
Most common conductor material.
What are metals?
Most common insulator material
What is a plastic spoon, comb, cloth, paper, wood, and glass?
P= w/t
What is the formula for power
an electrical circuit where the current flows through more than one path; if one path is interrupted, current will still flow through the other paths
What is a parallel circuit?
A magnetic field
What is the space around the magnet within which the force of the magnet can act
A semiconductor made from silicon and other semiconductors
What is a transistor?
A solid substance that has a conductivity between an insulator and most metals.
What is a semiconductor?
mass x acceleration
What is the formula for force?
a closed path through which electrons (electricity) flow
What is a circuit?
to be pulled toward an object by an invisible magnetic force
What is Atraction?
energy carried by a transverse wave a semiconductor device that acts like a one way valve to control the flow of electricity in electrical circuits.
What is a diode?
the earliest developed insulator
What is the pin insulator?
What is work?
W= f x d
an electrical circuit where the current has only one path; if the path is interrupted in any point, it stops the current flow in the entire circuit
What is a series circuit?
Magnetism
What is the invisible force that attracts objects containing iron, nickel, and cobalt?
property of matter that affects the flow of electricity; the opposition to the flow of electrons through a conductor
What is resistance?
Provides very high resistance to electric current so that it can’t flow through it.
What are good insulators?
Vf - vi /2
What is the formula for acceleration
Necessary for a circuit
What is a a source of voltage, a conductive path, and a resistor?
