Say the difference between resistance and resistor
The difference between the resistance and the resistor, the resistor, referred to as the resistor, refers to the real object of the charge flow; the resistance (Reactance), is an impedance of charge flow, usually used physical quantity
Rim
It is expressed. Its unit is ohm. Its size is usually called, or resistance values. The resistor is a physical quantity. This physical quantity is from the resistor. These two differences simply, a "object" and another means its "physical quantity".
Relationship between resistance and current
First, although there are several electrical nominals, among which is more, simple and popular say:
The flow of current-charge in the conductor is current.
Resistance – The resistance encountered when the charge is flowing in the conductor is called the resistance.
The difference between the potential between the two points in the voltage – circuit is the voltage.
Second, the relationship between resistance and current
In the closed circuit, when the voltage is added to the load on the load, the current size in the line is inversely proportional to the resistance value in the line, that is, when the voltage does not change and a fixed number, the resistance value in the line is large. When the current on this resistor is small, the resistance value in the line is larger in this resistor.
