Physiology of circulation as the total cross-sectional area of the vessels increases, the velocity of flow decreases four major factors interact to affect blood pressure: cardiac output, blood volume, peripheral resistance.

Cross sectional area affect the resistance

Simply put, air resistance what is air resistance article written: 17 may , 2016 updated: 17 may two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object. The electrons flow on the outer surface of the resistor, why then does the resistance of a resistor depend on it's cross sectional area and not on it's.

  • When the cross sectional area of the wire increases, the resistance decreases r=(resistivity coefficient x length)/cross sectional area.
  • As previously mentioned, the skin effect is where alternating current tends to avoid travel through the center of a solid conductor, limiting itself to conduction near the surfacethis effectively limits the cross-sectional conductor area available to carry alternating electron flow, increasing the resistance of that conductor above what it.
