Ohms Law and Resistance
Resistance:
defined as the ratio of the voltage across a conductor to the current flowing through the conductor.

It is a measure of how much the material of a conductor slows down the flow of the current (electrons)
Ohm's Law:
The relationship between voltage, current, and resistance of a conductor.

The equation: V = IR

V = the voltage (in volts)
I = the current (in amperes)
R = the resistance (in ohms)

Ohm: the unit for measuring resistance.
Resistor: a component of an electrical circuit that resists or opposes the flow of electrical current.
The resistor is the load in a circuit and converts electrical energy to another form of energy.
