Resistance of a Wire Introduction Theresistanceof a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential diff...
1) The resistance of a wire depends upon the material's resistivity, and the length and cross-sectional area of the wire. What will happen to the resistance of a wire if its length is multiplied by 2? The diameter of an aluminum wire is 0.2 m and the length is 200 ...
Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, theresistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current. Does resis...
First we have to understand the resistance of a wire for solving this problem: The resistance of wire is depends upon the material out of which the wire is made and also depends upon the length and cross-section area of the wire. Suppose L is the len...

(b) State the relationship between current, resistance and potential difference in a mathematical form. (c) Name the constant p whose value depends on the material of the conductor and give its SI unit. (d) How does value of p governs your choice of material to be used as live wire for...
The Resistance of the Wire:The resistance of the wire depends upon the length, area, and material of the wire. It is given by the following expression: {eq}\rm R = \dfrac{\rho L}{A} {/eq} where {eq}\rm \rho {/eq} is the resistivi...

Resistance is a fundamental concept in physics that quantifies the opposition encountered by an electric current flowing through a conductor. It is denoted by the symbol "R" and is measured in ohms (Ω). The resistance of a conductor depends on its mater
