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.
elecrical resistance means having something dimmed or brightened ( the lamp)
Equivalent series resistance (ESR) is an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components.
an ohm meter OR multimeter is used to measure the electrical resistance...
electrical resistance was discovered by Georg Ohm in the late 1820's.
Rheostat is the name of an instrument used to vary electrical resistance.
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.
Definition Of Resistance In Electrical:Property of a material to oppose the flow of electric current through it is called Resistance.
Equivalent series resistance (ESR) is an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components.
The electrical resistance offered by unit length and unit cross section of a material when a known voltage is applied at its ends.
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.
The ohm is the unit of electrical resistance. One ohm is the resistance when a potential difference of one volt produces a current of one ampere.
i dont know really, thats why im asking right
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.
