Resistance is the opposition to electric current, expressed in ohms.
Resistance is directly-proportional to the resistivity of the conducting material and its length, and inversely-proportional to its cross-sectional area.
Alternating current tends to flow towards the surface of a conductor due to the 'skin effect', thus reducing the effective cross-sectional area of a conductor. Therefore, resistance to a.c. is somewhat higher, at normal supply frequencies, than to d.c., and significantly higher at very high frequencies.

What is the definition of equivalent resistance?
Equivalent series resistance (ESR) is an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components.

Who when and how was electrical resistance discovered?
electrical resistance was discovered by Georg Ohm in the late 1820's.
What is the name of an instrument used to vary electrical resistance?
Rheostat is the name of an instrument used to vary electrical resistance.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
What is the meaning of electrical resistance?

What is the definition of specific resistance?
The electrical resistance offered by unit length and unit cross section of a material when a known voltage is applied at its ends.
What is meant by the resistance of an electrical component?
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
What is the Definition for ohms?
Ohm is the unit for electrical resistance. The definition is given by Ohm's Law: resistance = voltage / current; in SI units: ohms = volts / amperes. For example, a resistance of 1 ohm would result in 1 ampere of current for every volt applied.

One ohm is the SI unit of electrical resistance, representing the resistance of a conductor in which a current of one ampere is produced by a potential difference of one volt. It is named after the German physicist Georg Simon Ohm.
