What is electrical resistance?
Electric pressure or electric tension is the difference in electric potential between two points.
This charge is often carried by electrons moving through a wire.
The current through a conductor between two points is directly proportional to the voltage across the two points.
The electrical resistance of an object is a measure of its opposition to the flow of electric current.
What is the unit of measure for resistance?
Volts
Ohms
Watts
Amperes
What letter is used for resistance?
V
W
R
A
Does the resistance oppose the passage of?
The voltage
The train
The current
The wind
What formula is used to find the voltage?
V=2*R
V=I*R
V=R/I
V=R*I*W
What formula is used to find resistance?
R=V/I
R=3*R
R=V*I
R=I*R
What formula is used to find the current?
I=V*R
I=R/2
I=U*V
I=V/R
What is Ohm's law?
The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form
Law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force a phenomenon known as electromagnetic induction.
The electric force between charged bodies at rest is conventionally called electrostatic force
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
