When the length and area of cross section both are doubled the resistance will?
Initial length of the conductor l1=l Final length of the conductor l2=2l Initial cross-sectional area A1=A Final cross-sectional area A2=2A The resistance of conductors given by R=ρ1A∝1A As both the length and area are doubled Hence, there will be no change in the resistance of the conductor and so it will remain …
What happens to resistance when area of cross section is doubled?
What happens to resistance of a conductor if area of cross section is doubled? The resistance of a conductor is inversely proportional to its area of cross section. i.e., Resistance will be reduced to half.
When the area of cross section of a conductor is doubled?
Therefore, when the area of the cross-section of the wire is doubled, the resistance will be halved. Therefore, when the area of the cross-section of the wire is doubled, the resistance will not be doubled.
When both length and radius of a metallic conductor are doubled then its resistance?
Hence, if the length of a wire is doubled, then its resistance becomes doubled.
What happens to resistance of the conductor if length is doubled and area of cross-section halved?
Electrical resistance of any object increases with increase in its area of cross-section.
What happens to resistance of the conductor if length is doubled and area of cross-section halved *?
the resistance of a conductor is directly proportional to its length. now, the resistance of a conductor is inversely proportional the area of cross section. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. So your Resistance will become doubled.
What happens when you double the area of a conductor?
If you double both length and cross-sectional area of a wire, you will (double / triple / quadruple) the resistance of the wire. To cut the resistance of a wire in half, you may (cut the resistivity in half / double the length / quadruple the area).
When the length and cross-sectional area of a wire are both tripled the resistance?
If you double both length and cross-sectional area of a wire, you will (double / triple / quadruple) the resistance of the wire. 2. To cut the resistance of a wire in half, you may (cut the resistivity in half / double the length / quadruple the area).
How does resistance of a conductor vary with it’s a length and 2 area of cross-section?
Electrical resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). Resistance is inversely proportional to the area of cross-section. When the area of cross-section increases the resistance decreases and vice versa.
What happens to area when length is doubled?
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. Note: Otherwise the change in the value of resistance will occur due to the change in the cross sectional area also.
How do the length and cross-section area of a conductor affects is resistance of a conductor changes when I length is get half ii radius of wire is doubled?
1. Here, the resistance will decrease, as the length is halved (it means the length has decreased). 2. As the radius is doubled, the area of cross section is increased, and the resistance is inversely proportional to area, in this case too, the resistance will decrease.
When the area of cross-section of a conductor is doubled?
