why it is not necessary that small resistor is not physically smallin the size too?
Asked by pooja pujar | 21st Jun, 2011, 12:00: AM
The resistance of a conductor depends on the material, directly propotional to its length and inversely propotional to its cross sectional area.
R = ?l / A
A conductor having large length will have comparatively small resistance if its cross sectional area is very large.
