When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
You increase the length of leads of a capacitor by splicing extra length onto them.
All underground cables have relatively high values of capacitance, due to the close proximity of their cores and earthed (grounded) metallic sheath. Manufacturers provide data for their cables, which express their capacitance in terms of capacitance per unit length, e.g. microfarads per metre.Certain categories of underground cable-fault can be located by measuring the capacitance (using an appropriate bridge circuit) of the healthy section of the cable then, having determined the capacitance per unit length for that type of cable, measuring-off the distance along the cable route to the fault position.
With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.
If the length of a wire increases, the frequency of the signal it can carry decreases. This is because longer wires have more capacitance and inductance, which create a low-pass filter effect that attenuates higher frequencies. As a result, longer wires are less efficient at transmitting high-frequency signals.

If you increase the length then the width must decrease by the same amount if the perimeter is to remain the same.

When you increase the length of a lever, you increase the mechanical advantage of the lever. This means that you can exert less force to move the same load. Additionally, increasing the length of the lever can also increase the distance over which the force is applied, allowing for larger movements with less effort.
The capacitance of a cylindrical capacitor is determined by the formula C 2L / ln(b/a), where C is the capacitance, is the permittivity of free space, L is the length of the cylinder, b is the outer radius, and a is the inner radius.
In general the length of the leads contributes only a negligible amount to the capacitance of a capacitor. However at high enough frequencies excessive lead length can contribute an undesirable amount of parasitic inductive reactance, causing problems in circuit operation.

If you shorten the length of the string of a pendulum, the frequency of the pendulum will increase. This is because the period of a pendulum is directly proportional to the square root of its length, so reducing the length will decrease the period and increase the frequency.
The formula used to calculate the capacitance of a cylindrical capacitor is C 2L / ln(b/a), where C is the capacitance, is the permittivity of free space, L is the length of the cylinder, b is the outer radius, and a is the inner radius.
Assume that the increase in length is achieved by uniform reduction in the cross-sectional area of the wire. Then an increase in length by 4 times will result in the cross sectional area being reduced to a fifth of it original value. This will increase the resistance to five times its previous value.
