Is electrical resistance and electrical resistivity the same?

No. Resistivity is a material property, and is defined as the resistance for a piece of material of some standard size.


When current passes through a conductor what makes the conductor heat up?

The electrical resistance of the material. All materials have some electrical resistance except for superconductors.


What is insulating material used for?

insulating materials have low thermal/electrical conductivity values and hence can be used in applications where resistance to heat or resistance to the passage of electrical current is required.


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.

Yes.


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 are the Factors that determine resistance value of electrical material?

The factors that determine resistance are thickness, length, temperature, and the conductivity of the resistance of an object

Does resistance flow through a circuit?

No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.

Electrical resistance in a wire depends on the wire's?

It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.


What is resistivity of material?

the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
