Resistance will decreases... Because R is inversely proportional to Area of the conductor.
AnswerIf the conductor has a circular cross-sectional area, then doubling the diameter will reduce the resistance to one quarter of its original distance. This is because area is proportional to the square of the radius, and resistance is inversely proportional to cross-sectional area.
as the cross sectional area is halved, the resistance is increased by four times because the relation is R=(resistivity of materilal*length of conductor)/area of cross section of conductor
R= pL/A(p being the resistance value of the material). A =πr^2, if u reduce the diameter by 1/2, you'll quadruple the resistance
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.
this is because there will be more collisions between atoms and electrons as there is a greater distance to travel. The longer the length of wire, the more collisions. It is like a traffic jam, the longer the road, the loner you are stuck in it for.
P1 = V I1, Therefore, if P2=0.5*P1, thenI2=0.5*P1/V, or 0.5*I1and if P3=2*P1, thenI3=2*P1/V, or 2*I1In other words, current is proportional to power and inversely proportional to voltage.
The answer depends entirely upon the scenario. Are you dealing with AC or DC? Does your circuit contain passive components or both passive and active components?For example, if you a simply dealing with a resistive DC circuit, you can derive your answer from Ohm's law, V = IR. Rearranging for current, I = V/R, so if you double the voltage, the current is subsequently doubled.
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
The diameter of a circle is doubled if the circumference is doubled.
Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.
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 longer the conductor the greater the end to end resistance.
The circumference is doubled or tripled, respectively.
When the diameter is doubled, perhaps? Then the area is 4 x larger.
The volume of the cylinder would be doubled.
If you double the circumference. the diameter like wise would double.
It is halved. coz voltage=current * resistance
That has no effect on the resistance. The current doubles also.
the area is increased by 4 times
Impedance of a coil or a capacitor does depend on the excitation frequency,but resistance has no relationship to frequency.
