Electricity and Magnetisum
Electrisity
Electric current is a flow of charge
Charges can move from one place to another
Static charges have potential energy
Electric potenchal energy
electric potential
electric potencal
the electric potential energy per unit of electric charge at a specific point in an electric field, measured in Volts (Joules per Coulomb)
volt
the unit of electric potential difference, representing the energy per unit charge that drives electric current
Charge Movement
when a charge moves some of its electric potential energy is used in moving the charge and some can be used for other work
Lightning
Charge bildup
occurs in storm clouds as ice/water particles collide, separating positive (top) and negative (bottom) charges
Static distcarge
refers to the extreme electrostatic discharge (ESD) we know as lightning, caused by massive charge separation in clouds, creating huge sparks as electricity rapidly equalizes between cloud layers or ground
Charge Seperation
the fundamental process where positive and negative charges become distinctly separated within storm clouds (or volcanic ash), creating massive electric fields that discharge as lightning, driven by collisions of ice/water particles
Materials affect charge movement
electric charge cannot be moved easily through the air
conductors and isolation
conductor
a material that allows an electric charge to pass through it easily
insulater
A material that dose not easily allow a charge to pass through it
resistance
resistance
the properties of a material that determines how easily a charge can move through it
ohms
electrical resistance is measured in a unit called ohms
superconductors
many materials have almost no resistance at low temperatures these are called superconductors
Materials can become electricity charged
Electric charge is a property of matter
Electric charge
Scientific electric charge is a fundamental property of matter, carried by subatomic particles
Electric field
An electric field is a physical field surrounding electric charges, representing the capacity to exert forces
Static charges are caused by the movement not of electrons
Static charge
A static charge is an imbalance of positive and negative electrical charges on the surface of a material
Charge by contact
How materials affect static charging
Charging by induction
Induction
the process where a changing magnetic field creates an electromotive force (voltage) or electric current in a conductor
Charge polarization
Technology uses static electrisity
Magnetism
Circuits and electronics
