What would happen if the length of wire increase what happens to the resistance?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.

Thanks for the feedback!
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease) Since resist…ance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
The area of crossection decreases.If the wire is not ductile, the wire breaks.As resistance is directly proportional to length, the resistance of the wire increases.
Lets say the resistance of copper wire is 1 ohm per meter and the wire is 10 meters long then resistance of wire is 10 ohms* If we then theoretically take the resistance of th…e wire at 10 ohm* and the voltage from the source at 10V then the current would be* I=V/R 10/10 or 1A If we shorten the wire to 9m then resistance of wire is 9 ohms so current if V does not change would be I=V/R 10/9 or 1.111111111111111111111A *This is without loss or other factors
The resistance is indirectly proportional to the cross sectional area (thickness) so if the CSA doubles the resistance halves e.t.c In a nutshell as it gets thicker the resi…stance decreases.with regards to the formula :R=PL/A. R=resistance, P=resistivity, L=length, A=area.
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will caus…e an increase in resistance.
as with any electrical system if resistence is increases then current and voltage will be reduced.
capacitance also increase
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.RAO Answer If 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).
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.
The voltage drop across each resistance will go up, and the current through the circuit will go down.
By Ohm's Law Voltage = Current x Resistance If the Voltage input remains constant and the Resistance increases then the current will decrease proportionally.
The power consumed in any circuit is calculated by the formula P=V x I and as per ohms law we know that V=I x R, so placing the value of this Voltage in the power consumption …formula we get P=I2R. Thus whenever there is an increase in current in any circuit it implies that the power consumption of the load connected has increased. This may cause heat generation in the wire and possibly melt or burn the wire if the current exceeds the rated current of that wire.
What happens to the resistivity of the material of wire when the diameter of a metal wire is doubled keeping the length same?
Nothing. Resistivity, expressed in ohm metres, is a constant for any particular conductor although it is affected by temperature.
