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.
the current decreases
If the current in the wire increases, the magnetic field also increases.
the current will increase
The current capacity varies depending on the length and diameter of the 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 happens when the current in the coil is halved? No pins are attracted. ... A magnetic field is always created around a wire when it carries electric current.
If the current in the wire increases, the magnetic field also increases.
the current will 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).
increase
resistance increases
resistance of wire increases with increases of length
Other things being equal, a greater length will result in more resistance.
increase
It's resistance to electric current increases.
With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.
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.
As the resistance increases the temperature will also increases....
