PS Chapter 7 Flashcards
buildup of extra electric charge on an object
static electricity
charge can be transferred from object to object, but it can’t be created or destroyed
law of conservation of charge
a material in which electrons are able to move easily
conductor
a material in which electrons are NOT able to move easily
insulator
process of transferring charge by touching or rubbing
charging by contact
rearrangement of electrons on a neutral object caused by nearby charged objects
charging by induction

a device that can detect an electric charge
electroscope
when a charged object connects to the Earth through a conductor to have its charge rebalanced by getting or losing electrons
grounding
static discharge
spark or shock
a device to store a static charge
leyden jar
electroscope
a device that can detect an electric charge
grounding
when a charged object connects to the Earth through a conductor to transfer any excess charge between the object and the Earth
spark or shock
static discharge
leyden jar
a device to store a static charge
flow of electrons through a conductor
electric current
related to the force that causes electrons to flow
voltage difference
a closed path that electric current flows through
circuit
possible power source for a circuit
battery
tendency for a material to oppose the flow of electrons (changing electrical energy into another form)
resistance
unit for voltage difference
volts
unit for resistance
ohms
unit for current
amperes (or amps)
variable for voltage difference
