Electricity Flashcards
(54 cards)
What is charge
Electrons and protons
What is discharge
The lose of electrons to become neutral
What is a conductor
A substance or material that allows charge to flow through it
What is an insulator
A material in which electric currant does not flow freely
What is the current
The rate at which charged particles flows through the surface
What is a series circuit
Has all the components in one loop connected by wires
What is a parallel circuit
An electrical path with multiple branches
What is an electromagnet
It produces an electrical current
What did Benjamin Franklin demonstrate
The connection between lightning and electricity
How did Franklin do his test
He attached a wire to the top of the kite to act as lightning rod to the bottom of the kite he attached a hemp string and to this he attached a silk string
Location of a proton
Nucleus
Location of neutron
Nucleus
Location of an electron
Orbital shell
Charge of a proton
Positive
Charge of a neutron
Neutral
Charge of an electron
Negative
What do opposite charges do
Attract
What do like charges do
Repel
In a van de graff
When enough charge builds up between two points eventually the electrons jump across the air gap and it discharges the positive dome
What happens when the motor turns the bottom roller
The belt rubs on the brush at the top
Where are electrons transferred from in a van de graff
The brush and metal dome
Where are electrons transferred to
The belt and they are transferred off the belt by the lower brush
What is the result of the van de graff
The belt becomes equally charged with positive and negative charges
What happens when the dome is discharged
Electrons flow back onto it from a metal sphere creating a spark
