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
