What is Charging by Friction
Takes place when contact is made between a neutral object and a charged object
when static charges build up as different materials rub together
when a charged object is close to a neutral object, the electric field of the charged object produces an attractive force on the neutral object
What is charging by Contact?
When static charges build up as different materials rub together
When a charged object is close to a neutral object, the electric field of the charged object produces an attractive force on the neutral object
takes place when contact is made between a neutral object and a charged object
An insulator is a material in which electrons cannot move easily from one atom to another, what is an example
rubber
copper
aluminum
An electrical conductor is a material in which electrons can move easily between atoms
Water is both an insulator and conductor
like charges attract
Opposite charges attract
Charged and neutral objects repel each other
The electrostatic series
is a way to predict what charged will be gained by objects when they are rubbed together.
are a series of technologies that use static charges in order to accomplish a task
is a way to tell what is connected in parallel and what is connected in series
In a series circuit there is only one path in which electrons can flow
In a parallel circuit there is only one path along which electrons can flow
What is an electric current
A flow of electric charge. Is often carried by moving electrons in a wire. ( A ) Amperes ( I )
The difference of electrical potential between two points ( V ) Voltage
The difference of electrical potential between two points is
Electrical Current
Voltage
Resistance
What is the calculation of Ohm's law?
V=IR
R=V/I
I=V/R
All of the answers
An ammeter is connected in series in a circuit
A voltmeter is connected in series
How is the potential difference measured in series
Vt=V1+V2+V3...
Vt=V1=V2=V3...
How is the current measured in parallel?
It=I1=I2=I3...
It=I1+I2+I3...
What are examples of non-renewable energy sources
fossil fuels, coal, oil, and natural gas
wind energy,solar energy, geo-thermal
