If you double the length of the wire while keeping the resistance constant, the current will halve because resistance is directly proportional to the length of the wire. This is described by Ohm's law (V = I * R), where V is voltage, I is current, and R is resistance.

How Does the length of the wire affect its resistance?

As the length of the wire increases, the resistance also increases. This is because a longer wire offers more opposition to the flow of electrical current compared to a shorter wire. Resistance is directly proportional to length, so doubling the length of the wire will double its resistance.


Can you double the length of a metallic wire by applying force over it?

No, applying force to a metallic wire will not double its length. The length of the wire is determined by its physical properties and cannot be changed by force alone.


What is the relationship between current and length of a wire?

The relationship between current and length of a wire is inversely proportional when the resistance of the wire remains constant. This means that as the length of the wire increases, the current flowing through it decreases, and vice versa. This relationship is described by Ohm's Law, where resistance (R) is directly proportional to length (L) and inversely proportional to current (I).


If the wire is increased what should happen to the diameter?

If the wire is increased in length, the diameter of the wire should remain the same unless explicitly changed. The diameter of a wire is determined by its cross-sectional area, which is independent of its length.


How does the length of a wire affect the resistance?

Yes, resistance is directly proportional to the length, and inversely proportional to the cross sectional area. R = p*l/A. Where R is the resistance of the piece of conducting material, p is Greek letter rho, representing the resistivity of the material, l (lower case L) is the length, and A is the area.

What is the current carrying capacity of silver wire?

The current capacity varies depending on the length and diameter of the wire


Which is a better conductor between a short wire and long wire?

Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.


What happens to the current of the wire when the length increases?

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 effects resitance in a current?

length of the wire effects the resitance


When two terminals of 4.5 Voltage battery are connected by 100 meters long wire. the current in the wire is 50mA what will be the current from the battery when the wire is shortened 50 meters?

-- The resistance of the wire is proportional to its length. -- When the length is reduced by 1/2 , the resistance is also reduced by 1/2 . -- Reducing the resistance across the battery by 1/2 causes the current to double. -- The new current is 100 mA. (Assumes zero internal resistance in the battery, and that the 4.5 volts doesn't 'sag'.)


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.

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.
