l is the length of the conductor in meter (m)A is the cross sectional area of the conductor in square meters (m2) It is easy to understand this formula with water pipes analogy:when the pipe is longer, the length is bigger and the resistance will increase. when the pipe is wider, ...
21 Which of the following statements about the resistance of a pure metallic conductor is true when its temperature increases? The resistance of the pure metallic conductor A decreases because the metallic conductor will expand and its particles are less likely to obstruct the fiow of charges. B...
The effect of temperature on the resistance of the conductor isdirectly proportional to each other. The increase in temperature of the conductor increases its resistance and makes it difficult to flow current through it. As discussed above, the movement of free electrons creates the flow of current...
a在工作交接中存在很多不足的地方 Has very many insufficient places in the work connection [translate] aIn the film thickness increases, the resistance increases quickly, is a film become poor conductor. di aumenti di spessore di pellicola, la resistenza aumenta rapidamente, è una pellicola si ...
The first law is represented by the statementR αL. This means, if the length of the conductor increases, the resistance also increases. In the same way, if the length of the conductor decreases, the resistance decreases. Second Law
electric current is the rate of flow of electrons inside a conductor. its si unit is ampere. q4 what happens to the resistance of a wire if its length is decreased? as resistance is directly proportional to the length of the conductor, the resistance will decrease with the decrease in the...
If the resistance of the conductor is \(R\) and there is a current \(i\) flowing through it, then from Ohm’s law, \(i = V/R\) Now, if two such conductors are joined end to end, i.e. in a series combination: The effective length of the conductor increases while the area of...
Where, ρ (rho) is the proportionality constant and known asresistivityorspecific resistanceof the material of theconductoror substance. Now if we put, L = 1 and A = 1 in the equation, we get, R = ρ. That means resistance of a material of unit length having unit cross – sectional ...
How does the resistance of a conductor affect current flow? Voltage is the measure of the electrical potential that allows electrons to go through a circuit in the form of current. The transfer of power and the functioning of electrical equipment depends on current and the movement of electric ...
The resistance of a conductor depends on several factors, including the material of the conductor, its length, its cross-sectional area, and the temperature at which it operates. How does the length of a conductor affect resistance? The resistance of a conductor is directly proportional to its ...
