Flashcards in Physics 2 Deck (18):
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 gained electrons it is a what charge?
If object has lost electrons it is a what charge?
Hair sticking on brush
Law or charges States that
Opposite charges attract
Likes charges repel
Static electricity is produced by
Friction between two different materials
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?
Complete circuit made by conducting materials
Where charged flow along a path
Voltage is ? EMF
A measure of the amount of energy available to push charges around a circuit.
Measure of how much energy is transferred or used by a load
Voltage in parallel
The voltage is the same across all branches
Series in voltage
The voltage is shared
The current splits at each branch and thy add up to the total current
