∙ 13y agoA piece of wire stretched such that its length increases and its radius decreases will tend to have its resistance increase. The formula for this is: R = ρL/A where ρ = resistivity of the material composing the wire, L = length of the wire, and A = area of the conducting cross section of the wire. It can easily be seen that as area decreases resistance gets higher. In the case proposed the wire length is not reduced as it is stretched to reduce the area, this increases the resistivity as well.
A: there is no formula the gain of the amp is just reduced by the transformer turn ratio minus efficiency or loss. the transformer is for isolation and impedance matching
From the formula, E = V/d, where V is the voltage and d is the distance, it can be seen that the electric field and the distance are inversely related. Thus, as the distance between the parallel plate capacitors is reduced to half, the electric field is increased twice. Moreover, is a dielectric constant k is introduced, the capacitance will increase. This direct relationship can be seen in the formula, C = [k(Єo)A]/d, where k is the dielectric constant. The lowest possible value of k is 1; and that is when the dielectric is a vacuum. Other dielectric constants are greater than 1, such as teflon which has a dielectric value of 2.1 As the capacitance increases, the electric field also increases. (E = 1/2(CV^2))
The corrosion on iron can be reduced by suitable thin layer of element to be electroplated.
Primarily, lower manufacturing costs due to the elimination of wastes. Also, lean tecniques encourage production to be better matched to demand, which can result in improved response to customers. Overproduction is one of the wastes reduced or eliminated (and really the worst of them), and improved customer response and no overproduction can result in more control over pricing and margin. So, costs are reduced and revenues may be increased in a successful lean enterprise.
The resistivity of copper at 77 K is approximately 1.7 x 10^-8 ohm-meters. At lower temperatures, the resistivity of copper decreases due to reduced scattering of electrons by lattice vibrations.

A reduced blood flow to the kidneys
A change in temperature generally increases the resistivity of most materials. This is because as temperature rises, the atoms in the material start to vibrate more vigorously, causing more collisions between electrons and atoms. These collisions impede the flow of electrons, resulting in an increase in resistivity. Conversely, at lower temperatures, resistivity tends to decrease due to reduced atomic vibrations and fewer collisions.
A fully reduced fraction is the one which is reduced to the lowest terms by finding an equivalent fraction in which the numerator and denominator are as small as possible.
