Resistance depends on the thickness and length of the wire used, as well as the conductor used. For example, a short, thick wire made of copper will conduct electricity better than a long, thin wire made of, say, iron.
AnswerResistance is directly proportional to the length and inversely proportional to the cross-sectional area (not 'thickness') of a material. Its constant of proportionality is called resistivity which is affected by temperature -so temperature indirectly affects resistance.

Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
Is the resistance lower if you have a high current?
Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.
How does a resistance of a wire depend on its radius?
Resistance is inversely-proportional to the cross-sectional area of a conductor. For example, doubling its cross-sectional area will halve its resistance, while halving its cross-sectional area will double its resistance.Since the cross-sectional area of a circular-section conductor is proportional to the square of its radius, doubling that radius will reduce its resistance by one quarter, while halving its radius will quadruple its resistance.
If you know the current through one resistor in a DC circuit then do you know the current through all the other resistors?
No. Current and voltage are directly proportional to one-another and both are related to resistance by Ohm's law: V = IR or Volts = Current * Resistance So the current will depend upon the voltage and the circuit resistance by rearranging the above equations: I = V/R Meaning that the current will decrease as circuit resistance is increased if the voltage remains constant.
Dc resistance of diode is a static resistance b dynamic resistance c high resistance d zero resistance?
B - Dynamic resistance
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
Why resistance doesnot depend on frequency of ac?
Because Resistance is material property...
How does current depend on resistance?
Pressure from the voltage.
What material does resistance depend on?
guns and money
Does air resistance depend on weight?
No, only on the shape.
What does the size of the current depend on?
A: The EMF and total resistance
What is the temperature of resistance spot welding?
It is depend on machine
Relation between voltage and RPM?

Do resistivity depend upon area of crosss-section?
No. Resistance does.
Does the resistance of a wire depend on the cross section area of the wire?
Yes. The bigger the cross section, the lower the resistance.
What happens to the resistance when the frequency is doubled?
Impedance of a coil or a capacitor does depend on the excitation frequency,but resistance has no relationship to frequency.
