It will be appreciated that the formula for the resistance of the resistor and the length of the material is:

R＝ρ.L/S，

where ρ is a proportionality constant, ρ is a physical quantity related to the material of the conductor and reflecting the conductive property of the material, and is called the resistivity of the material. R is the resistance of the resistor, L is the length, and S is the cross-sectional area.

The relationship between current and resistance is formulated as:

I＝U/R，

in the formula, I is current, U is voltage, and R is resistance, and the formula shows that the resistance R is inversely proportional to the current I, and the larger the resistance R is, the smaller the current I is.
