Physics 2 Flashcards
If object has gained electrons it is a what charge?
Negatively charged
Static electricity is
The buildup of charge on a surface as a result of gaining or loosing electrons through friction with another surface
If object has lost electrons it is a what charge?
Positively charged
Static situations
Hair sticking on brush
Electric shock
Escalator
Law or charges States that
Opposite charges attract
Likes charges repel
Static electricity is produced by
Friction between two different materials
Electrostatic. Induction
Temporary buildup of charge on a neutral object due to the presence of a charged object
Explain why spray painting with a charged object is better to use?
The charged object will induce a charge on the paint droplets and the object will attract the paint making it unwasted
What do current electricity need?
Voltage source
Complete circuit made by conducting materials
A load
Current electricity
Where charged flow along a path
Conductors examples
Copper
Aluminium
Graphite
Iron
Insulator
Glass
Plastic
Wood
Rubber
Voltage is ? EMF
A measure of the amount of energy available to push charges around a circuit.
Potential difference
Measure of how much energy is transferred or used by a load
Voltage in parallel
The voltage is the same across all branches
