Resistance

RESISTANCE PARAMETERS:
1) Length (L)
2) Cross Section Area (A)
3) Material (ρ)

Longer the wire the more resistance
The greater the cross-section area the less resistance

LENGTH

Resistance is directly proportional to the length
R ∝ L

CROSS-SECTIONAL AREA

Resistance is indirectly proportional to the Area
R ∝ 1 / A

MATERIAL

Resistance is indirectly proportional to the material
R ∝ ρ x L / A
