Magnetism
property of a material that describes its ability to exert a force on a magnet or a magnetic material.
magnetic
What is electricity?
flow of electric current through a conductor, such as a wire. Electricity is sometimes also used to describe electrostatic charges.
continuous flow of electrons
electric current
electromagnet is
when electricity and magnetism meets
solenoid
coil of wire, usually cylindrical, that uses electric current to create a magnetic field.
When the north pole of one magnet meets the south pole of another magnet, they _______each other.
attract
A law to mathematically describe the relationship between current, resistance, and voltage of electrical circuits.
What is Ohm's Law
closed pathway that an electrical current follows
circuit
poles are
the strongest part of the magnet
Like electric charges, opposite poles of a magnet _________ each other.
Attract
two regions in a magnetic field
magnetic poles
decreases
types of circuit
parallel, series circuit
static energy is
the build up of electric charges on an object
Find the current of a transformer connected to 120 V with a resistance of 480 Ω.
What is 0.25A
A circuit in which parts are connected so that the electric Current passes along more than one pathway.
What is Parallel Circuit
It is the flow of this subatomic particle that generates electricity.
Electron
supplies used to make circuit
batteries, wires lightbulb
how are current and voltage related
directly
machine that transforms or converts electrical energy into mechanical energy.
Electric motor
vector arrows that depict visually the direction and magnitude of an electric field
electric field lines
the units of electrical current and resistance
ampere,ohm,
If you add more ligth bulbs to this type of circuit, the lights grow deemer.
series circuit
the flow of electrons along a complete closed path
current electricity
