Resistance is the property of a material to oppose or slow down the flow of charges. So how does it dependon the dimensions of a material?
A: The magnitude of resistance is dependon cross section of the wire the material constructed with and the additional strands ofwire involved. Answer Resistancedepends upon the length, cross-sectional area, and resistivity of a conductor.

The New topic theresistanceof a wiredependson the is one of the most popular assignments among students' documents. If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples.
An electron traveling through the wires and loads of the external circuit encounters resistance. Resistance is the hindrance to the flow of charge.
The longer the length of the wire, the higher theresistance. This is because there are more positive ions in the metal so there is more chance that
A wire's resistance dependson four main factors
The length of the wire on the other hand could not have been very accurate, being that it was cut by the judgement of an human eye, this could have
We can say that resistancedependson area of cross section.Now complete the circuit with copper wire of a length l, and same thickness equal to nichrome wire. And observe the ammeter reading, say i4 = 3A.We can say that i4 is greater than i1.
- Investigating theResistanceof a WireResistanceof a Wire Task To investigate how theresistanceof a wire is affected by the length of the wire.
Answer: 1) (a)Resistivity is the property of a material. So it is indepentdent of temperature. Hence resistivity remains same with increase or d...
Theresistanceof a wire is inversely proportional to its cross-sectional area.
Theresistanceof a wiredependson certain factors. Some of these variables are listed below
ResistanceOfWire. If you increase the voltage - more current will flow.
Resistanceof a wiredependson the Length and cross-section of the wire.
To calculate theresistanceof the wire I will divide the voltage (V) by the current (I), which will give me theresistance in ohms (W).
Principle Theresistanceof a short thick wire is different to that of a long thin one. Tasks Examine how the value of theresistanceof a wiredependson its length and cross-sectional area.
Resistance:- A peculiar property of a conductor which obstruct the flow of electric charge is called resistance.
Theresistanceof the wiredependson the following factors.
Much Constantan Wire Is In The Circuit? Essay, Research Paper Aim The aim of this experiment is to investigate or find out how theresistanceof a wire is affected by
Theresistanceof an object (i.e., a resistor ) dependson its shape and the material of which it is composed.
Resistancedependson the material the wire is made of. The more tightly an atom holds on to its outermost electrons the harder it will be to make a current flow. The electronic configuration of an atom determines how willing the atom will be to allow an electron to leave and wander through the lattice.
Since theresistanceof some conductor, such as a piece ofwire, dependson collisions within the wire itself, theresistancedependson temperature.
In effect, the resistivity represents theresistance across two opposite faces of a cubic metre of
The electrical resistanceof a material is a measure of how the material impedes the flow of electrons through it. For a fixed EMF across a wire, a higher resistance results in a smaller current flowing. Theresistanceofwiredepends upon several factors
Material ofwire - wires of different densities will block more or less electrons Temperature - the vibration of warm molecules makes them more
The number of free electrons dependson the material and more free electrons means a better conductor, i.e. it has less resistance.
AIM To determine theresistance per cm of a given wire by plotting a graph of potential difference versus current.
This model demonstrates how to compute theresistanceof a short section of copper wire.
The longer a piece ofwire the higher its resistance. Double the length means double theresistance.
Theresistanceof a given piece ofwiredepends of three factors: the length of the wire, the cross-sectional area of the wire, and the resistivity of the material composing the wire. To understand how this works, think of water flowing through a hose.
Length ofwireTheresistance changes with the length ofwire. ... Scientific Knowledge Background information about the wires that I am investigating The table below gives some data about the
The amount by which a resistor resists the flow of charge is quantified as resistance $R$.
Theresistanceof a wiredependson its length, its cross sectional area and on the material it is made from.
2 Resistance Resistanceof a wiredependson: Composition. The particular substance from which the object is made. Length. The longer the wire, the higher theresistance.
The direction of the air resistance force is in the opposite direction as the velocity of the object.
