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.
Why does heating effect of electric current happen?
When an electric current flows through a conductor, the electrons collide with atoms in the material, transferring energy in the form of heat due to resistance. This resistance causes the material to heat up, a phenomenon known as Joule heating. The heating effect is a result of the conversion of electrical energy into thermal energy.
What is the dependent variable when testing the conductivity of wood and lead?
The dependent variable is the one you measure. In this case, it would be the electrical resistance, measured in Ohms.An easy way to remember is to note that the resistance changes based on the material. The resistance is dependent on the material used, and thus the resistance is, in this case, the dependent variable.
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. 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.There are many different types of resistance, and I recommend that for starters you read up on the Wikipedia article on electrical resistance.http://en.wikipedia.org/wiki/Electrical_resistance
Do bends in a wire effect its electrical resistance?
Yes, bends in a wire can increase its electrical resistance due to the deformation of the metal lattice structure, which interrupts the flow of electrons. This increased resistance can lead to energy losses in the form of heat.
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 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
Does temperature increase affect resistance?
Yes. The exact effect - whether it increases or decreases - depends on the material.
Do bend in the wire effect the electric resistance?
Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.
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.
How energy is transformed in electric flat iron?
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.
