Which part of the electric stove produce the heating effect?
A heating element. That is made out of high electrical resistance material. As electricity pass through the element a high amount of resistance is encountered, thus heat is created.
What is effect of temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
What is resistance?
Resistance is the opposition to flow or movement.Resistance in a a mechanical system could be friction, wind, gravity.Resistance can be opposition to a policy, or to an invasion (e.g. French Resistance).Resistance in an electrical circuit is the limiting or opposition to current flow. It is measured in Ohms.----Electrical ResistanceThe technical definition is "Electrical resistance is a ratio of the degree to which an object opposes an electric current through it, measured in ohms."In simplfied terms, electrical resistance is broadly equivalent to friction in a mechanical system. If you applied a voltage to a circuit with zero resistance then you would get an infinite current. In reality all circuits have some resistance which limits the current.We can predict the current in a given circuit using Ohms law:V = I x RWhere:V is Voltage (measured in Volts)I is current (measured in Amps)R is resistance (measured in Ohms)You will often see this in the form E = I x R. It is exactly the same thing, just a different convention where "E" is used for voltage instead of "V"Ohms law is:V=I/RV=Voltage (volts)I=Current (amps)R=Resistance (Ohms)Resistance in an AC circuit is called Impedance (Z)Electrical resistance is the amount that an object opposes electrical current. All things being equal (temperature, purity, etc.), resistance is a function of both its physical geometry and the resistivity of the material it is made from. Impurities in materials and fluctuation of temperature can effect the amount of resistance a material will exhibit.----------Electrical resistance is the amount that an object opposes electrical current.

What effect does it have on the voltage drop in an electrical cable if the resistance of the cable is decreased?
It will decrease the voltage drop.
What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What is optical and superconducting materials?
Superconduction is a term that describes a material that has zero electrical resistance. This is significant because even good conductors like copper or gold always have some electrical resistance. Superconduction is an effect that only happens when particular materials are extremely cold (think liquid nitrogen). The effect is used in generating powerful magnetic fields in MRI machines. Optical conducting materials (also known as waveguides) are a material that transmit light using a process called total internal reflection. Optical fibre cable is a common example of an optical conductor.
Does temperature increase affect resistance?
Yes. The exact effect - whether it increases or decreases - depends on the material.
What affects electrical resistance?
Primary Factors:For a simple system like an electrical wire, there are three major things which will affect the electric resistance.1. Resistance of wire conductor depends upon the material of which it is made.2. Resistance of wire conductor is directly proportional to its length.3. Resistance of a wire conductor is inversely proportional to its area of cross-section. (At least for low frequency voltage.)Additional:In general every material has a characteristic electrical conductivity (and resistivity) which determines how well it will conduct electricity. Metals have very high conductivities and insulators very low. The geometry of an object affects the resistance with the above-mentioned wire geometry being the most important example.In general the type of material and the geometry are the primary factors in determining the resistance of an object, but there are other effects worth mentioning.Temperature can change electrical properties of a material and there are some dramatic examples such as superconductors. Semiconductors can also have important temperature dependent properties. For most generic materials there is a rise in resistance with an increase in temperature but the effect is not usually large.More exotic phenomena also exist, such as the change in resistance due to a magnetic field or nonlinear conductors which do not have a fixed resistance but rather have a resistance that depends on voltage. Conductivity through a gas is a dramatic example of the latter.
What effect did World War 1 have on writers and painters and musicans who worked in the postwar years?
they started writing, painting and composing more bleak material than before! -bluecow798
How electric flat iron energy is transformed?
An electric iron has a heating element that offers electrical resistance. The resistance causes friction to occur in the electrons and causes a heating effect.
