how does the resistance of a wire change when a) its
22/12/2012 · A practical application of rho = RA/L for calculating the resistance of a length of copper wire. A practical application of rho = RA/L for calculating the resistance of a length of copper wire... is doubled, R1 + R2 +R3 + Rn = Rtotal therefore 2 X Rwire= 2 X Rtotal. Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire.

Other wire gauge systems exist in the world for classifying wire diameter, such as the Stubs steel wire gauge and the Steel Music Wire Gauge (MWG), but these measurement systems apply to non-electrical wire …... What will happen to the resistance, when the diameter of the conductor is doubled?.. Answer / v muralidharan The question is incomplete.It should specify if the length is the same when diameter is doubled.
The Relationship Between Length Width and Resistance of a
?why of length 15 cm is 10 resistance in a circuit find the resistance of a wire if the wire is stretched to double its length the wire is doubled on itself? how to know what wall mount to buy We know that, the resistance of a wire (a)if length is tripled: Hence resistance also gets tripled. (b)if diameter is tripled :d'=3d . New resistance will be 1/9 times of original resistance. (c)if resistivity is three times the original resistivity: 36 ; View Full Answer. when the length is tripled the resistance will be thrice the previous resistance. when the daimeter is tripled the
how will the resistance of a wire change if its diameter
Looking at our wire size table, we find that 14 gauge wire has a cross-sectional area of 4,107 circular mils. If we’re still using copper as a wire material (a good choice, unless we’re really rich and can afford 4600 feet of 14 gauge silver wire!), then our specific resistance will still be 10.09 Ω-cmil/ft: how to find capacity of a cylinder Replacing a wire resistor with another of the same material and length but with three times the diameter will have the effect of changing the resistance by what factor? 1/9 must be parallel to current flow.

How To Find Resistance Of Wire When Diameter Is Doubled
A certain wire has resistance R. What is the resistance of a second wire, made of the same material, which is half as long and has 1/3 the diameter? Solution: The resistance is proportional to the length of the wire and inversely pro-portional to the area. Since area is proportional to diameter squared, the resistance is Rnew = R=2£9 = 9R=2 1. 4. A circuit contains a resistor R in series with
- Wire Gauge Calculator. Online AWG diameter calculator to find the diameter of the wire in gauge (AWG). Wire gauge is nothing but the measurement of length of the wire, in either of diameter …
- An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length - An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length Introduction In this investigation I hope to see whether there is a relationship between the thickness of a wire and its length
- is doubled, R1 + R2 +R3 + Rn = Rtotal therefore 2 X Rwire= 2 X Rtotal. Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire.
- 17/05/2007 · resistance will be equal to resistivity only if a wire with length = 1m and cross-sectional area is = 1m sq R=r l/A where R is resistance, r is resistivity, l is length and A is cross-section.
