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.

What happens to voltage when wire length 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.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).

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 else increases as energy carried by a current increases?

The amount of electric energy that is converted into thermal energy increases as the resistance of wire increases. As the resistance in the current increases, the current in the circuit decreases.


How is a current affected across a wire if its resistance increases?

As the resistance increases the temperature will also increases....
