Red group - Electricity 3
protons have poseetive charge
electrons have negative charge
neutrons have neutral charge
electricity is the movement of electrons
protons, neutrons & electrons are sub-atomic particles.
Atoms are electrons,neutons and pprotons
conductors and insulators
protons & electrons attract each other, whereas two atoms with the same charge repel each other.
insulators are usually non metal
Electrical circuts
The flow of electrons
when two objects are rubbed against each other, one object becomes negatively charged, unlike its surroundings.
opposite charges attracks to eachother
static electricity
curent electricity
when an electric current flows through a wire, a magnetic field is created around it.
when an object has an equal amount of protons & electrons, they cancel each other out.
electricity
series share the voltage equaly with all the
parallel cicuts have the same voltage on all the
we messure circuts using Amps and volts
Amps tell us how fast the electricity moves
Votage tells us how much pressure the circuit has
metal is a conductor
a direct current is usually powered by batteries, while alternate currents are powered by electric generators, which are usually more effective.
current is measured in amperes
The pressure in the circut is meassured in voltage
