Electricty Flashcards
The charge on an electron.
-1
Electricity
Ohm’s law
The current in a circuit equals the voltage difference divided by the resistance
Like charges ______________
Repel
These bulbs are hooked up in _____________.
These bulbs are hooked up in series.
What are the blue and red particles
Protons and Neutrons
Electricity
Law of Conservation of charge
Charge can be transferred from object to object, but cannot be created or destroyed
Ohm’s Law
V = IR
(often written I = V/R)
One Joule per coulomb is known as
One Volt
A battery is a device that converts
___________ to ___________.
A battery is a device that converts
chemical potential energy to electrical energy.
Which particles typically flow in a circuit?
(Electrons, protons, or neutrons)
Electrons
(they are on the outside edges of the atoms, and can jump from atom to atom if they are not held too tightly by the nucleus.)
A material in which the electrons on each atom are held onto very tightly by the nucleus.
Insulator
What are the orange particles, and what is their charge?
They are neutrons
The have no charge.
The three particles that make up atoms.
Protons
Neutrons
Electrons
Electricity
Conductor
A material in which electrons are able to move easily.
Electricity
Charging by induction
The rearrangement of electrons on a neutral object caused by a nearby charged object
A material in which the nucleus only loosely holds onto the electrons on the surface of the atom.
Conductor.
A method of charging an object where you scare the electons away, leaving a positive area behind.
Charging by Induction
Electricity
Electric current
The net movement of electric charges in a single direction
These bulbs are hooked up in _____________.
These bulbs are hooked up in series.
The charge on a proton.
+1
Electricity
Series circuit
The current has only one loop to flow through
What are the little grey particles?
Electrons
Electricity
Resistance
The tendency for a material to oppose the flow of electrons
What are the yellow particles?
Protons
What are color are the neutrons?
Green
Electricity
Circuit
A closed path that electric current follows
These batteries are hooked up in _____________.
These batteries are hooked up in Series.
Electricity
Static electricity
The accumulation of excess electric charges on an object
An ampere is equal to
1 coulomb of charge per second
Ampere = Coulombs/Second
What are color are the electrons?
Blue
Electrical Potential Difference is also known as….
Voltage
(Voltage is measured in Joules/Coulumb)
Electricity
Parallel circuit
Contains two or more branches for current to move through
Electricity
Insulator
A material in which electrons are not able to move easily
A method of charging an object where electrons are pulled to the surface, making the surface negativily charged.
Charging by Induction
Electrical Current is measured in
Amperes (amps)
What are the whitish particles?
Electrons
What are the blue and red particles deep down in the nucleus of an atom?
Protons and Neutrons
Electricity
Electrical power
The rate at which electrical energy is converted to another form of energy
Electricity
Charging by contact
The process of transferring charge by touching or rubbing
Opposite charges _____________.
Attract
The charge on a neutron
0
These batteries are hooked up in _____________.
These batteries are hooked up in parallel.
Something that opposes the flow of electricity in a circuit.
Resistor
(could be a lightbulb, a very thin wire, a home appliance like a toaster or dishwasher)
Electricity
Voltage difference
Is relating to the force that causes electric charges to flow
What are color are the protons?
Red
