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.
How much voltage a piezoelectric crystal can produce?
The current will depend on external resistance - far better to consider total energy, conversion efficiency, or failing that, voltage. The answer will depend on device size anyway.
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.
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
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
What is the metric unit of a thumb?

Do resistivity depend upon area of crosss-section?
No. Resistance does.
Does the induced current depend on the resistance of the circuit?
In general, yes, it does. For example, if you move a conductor in a magnetic field, this will induce a certain voltage between the extremes of the conductor; the corresponding current will then depend on the resistance.
Why do each substance have different amount of resistance?
Resistance of a material is depend on the force required to withdraw electrons from the atoms of that material.
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
Does electrical resistance depend on temperature and bias voltage?
Electrical resistance depends on the temperature but not the biased voltage.AnswerIt's resistivity that can be affected by temperature, which means that resistance is indirectly affected by temperature.
