Assuming that there is a potential difference across the conductor, then the value of the current will fall (I = E/R).

Nothing. Resistivity, expressed in ohm metres, is a constant for any particular conductor although it is affected by temperature.

If you mean the length of the wire that supplies current to the bulb, the bulb will dim due to increased resistance in the wire, if you make it longer.

Actually resistance is directly proportional to the length provided area remains constant. But as we stretch the wire only its volume would remain constant. So its area is to …be decreased as length increases. V = pi r^2 * LNow we have R = K * L / pi r^2Multiplying numerator and denominator by L we get R = K/V * L^2So resistance is found to be proportional to square of lengthHence as length gets increased by 2 times, its resistance value would increase by 4 times.

A 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 = resis…tivity 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.

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 t…he 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.RAO AnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothing happens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire). (MORE)

-- A piece of wire behaves like a resistor. Granted, its resistance is very small, but it has some. -- Another piece of wire behaves like another resistor. Granted, its resi…stance is also very small, but it has some. -- When you twist one end of each piece of wire together, you get a longer wire. Also, electrically, you have connected two resistors in series. As you know, the total resistance of resistors connected in series is the sum of the individual resistances, and is greater than either single resistance alone. (MORE)
