Does length of wire affect current?
The relationship between resistance and wire length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional .
What happens to the current if the length of the wire is doubled?
Hence, If the length of a wire is doubled, then its resistance becomes 2 times.
When length of wire is doubled What is the change in resistance?
What happens to resistance when length is doubled? From the equation, we understand that resistance is directly proportional to the length of the conductor and inversely proportional to the crossectional area of the conductor. Doubling the length doubles the resistance.
How does the resistance of wire change when 1 Its length is doubled 2 area is doubled?
Complete answer: Also, let A be its cross sectional area. So, the new resistance, after doubling the length of the wire, becomes twice of the original resistance. Hence, if the length of a wire is doubled, then its resistance becomes doubled.
What happens to the resistance if the length is halved?
The answer :If the length of the wire is halved, it’s resistance also gets halved. Reason: Resistance is directly proportional to length of the conductor . Hope it was helpful.
Can a copper wire and an Aluminium wire of the same length have the same resistance?
If aluminum and copper wires of the same length have the same resistance, which has the larger diameter? Copper has a lower resistivity than aluminum, so if length is the same, copper must have the smaller diameter.
Will a copper or aluminum wire of the same length and thickness allow more electric current to pass through?
The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. This is due to the fact that the resistance of a wire is inversly proportional to the square of its diameter.
What diameter aluminum wire will provide the same resistance?
1.12 mm
