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.

Answer

If 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).

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.

What is effect of voltage and current by changing the length of wire?

By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.

What will happens to current when cable length increases?

With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.


What happens to the electric current in a wire when voltage is increaced?

If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.


Can you list three ways you can change the current in a circuit?

Increase, decrease, or remove the load <<>> Change the voltage and the current will also change in direct proportion, Ohms law.


What is the relationship between wire size length of run and voltage drop?

The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.


Relationship between the length of wire and its electric current?

The electrons in a conducting wire are loose and can move freely. When the circuit is closed, a potential difference is set up across the terminals. The battery maintains this potential difference. Then the electrons in the wire move towards the positive terminal of the battery. This flow of electrons constitute the electric current.


How the length and thickness of wires could affect the brightness of light bulbs?

Voltage loss. On a long run you will loose some voltage so it is sometimes necessary to increase the wire size to compensate for the voltage loss. This loss of voltage will cause a light to be dim as it is not receiving the correct voltage that is was designed to use.


Does the length of the wire affect the brightness of the bulb?

Wire has a certain amount of resistance. As electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp. So, the longer the wire, the less voltage the lamp gets, and the dimmer it will be.

What happens if electricity travels long distances?

Increased wire or cable length causes the voltage to drop, this loss of charge is converted to heat and can cause electrical fires and damage to electronics.
