Resistance is defined as a property of materials due to which a material opposes the flow of current through themselves. And Resistance is inversely proportional to area of cross section of conductor. As the cross section area of thin wire is less hence resistance is more. So, as wire diameter increases its resistance decreases and vice versa

What is an electric arc diameter as function of the current?
The electric arc diameter is directly proportional to the square root of the current passing through it. This relationship is described by the formula D = k√I, where D is the arc diameter, I is the current, and k is a constant factor. Increasing the current will result in a larger arc diameter, while decreasing the current will lead to a smaller arc diameter.
How are resistance and the diameter of a wire related?
Resistance is inversely related to the diameter of a wire. A larger diameter wire will have less resistance compared to a smaller diameter wire, assuming other factors like length and material remain constant. This is because a larger diameter wire provides more space for electrons to flow through, resulting in less resistance to the flow of current.
What happens to resistant if wire diameter is decreased?
If the wire diameter is decreased, the resistance of the wire will increase. This is because with a smaller diameter, there is less cross-sectional area for the electrical current to flow through, causing more hindrance and resulting in higher resistance.
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, the wire with a diameter of 0.01 mm will have higher resistance compared to a wire with a diameter of 0.1 mm. Resistance of a wire is inversely proportional to its cross-sectional area, so a thinner wire will have higher resistance.
What is the effect on the projectile motion when the diameter of the object is changed?
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.

Unit of electric resistance?
The unit of electric resistance is the ohm, represented by the symbol Ω. It measures the opposition that a material has to the flow of electric current through it. Smaller resistances allow for a larger current flow, while larger resistances restrict the current flow.
Do thicker or thinner wires have more Resistance?
Over the same distance the larger diameter wire will have less resistance that the smaller diameter wire.
The flow of electricity can be compared to the circulation of water in a?
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
What happens to an electric current when the wire is made smaller?
Electric current as we usually describe it is the flow of electrons. Current is caused to flow by voltage, which can be looked at as "electrical pressure" that forces electrons to move. Currents can be made smaller or larger by decreasing the voltage across a fixed amount of resistance. As resistance is the quality of "resisting" or "limiting" current flow, we can change resistance to change current. For a give voltage, if we increase the resistance, we can make the current smaller, and if we decrease it, we can make current larger. In electronics, voltage equals current times resistance. E = I x R Also true is that current is equal to voltage divided by resistance. I = E/R As current equals volts divided by resistance, if we change one of them without changing the other, current will change. And in increase in voltage (with no change to resistance) will cause current to go up. The opposite is also true. Also, if we increase resistance (with no change in voltage), current will go down. And the opposite is true here, too.
What is current and types of currents?
Current is the amount of electriticy that flows through a conductor. The electric current is determined by two factors: The voltage applied to the circuit, and the diameter ( circular area in mm2) of the wire (conductor). More voltage, more current, the same voltage in a smaller diameter of the wire = less current. / less voltage = less current. / smaller diameter of the wire = more resistance> less current. Load inserted in the circuit has a resistance measured in Ohms = more resistance of the load ( a lamp, for example) = less current. / larger diameter of the wire= more current, because it has less resistance. / All can be easily calculated using the Ohm Law =The interchangeability of the equation may be represented by a triangle, where V (voltage) is placed on the top section, the I (current) is placed to the left section, and the R (resistance) is placed to the right. The line that divides the left and right sections indicate multiplication, and the divider between the top and bottom sections indicates division (hence the division bar).Direct currrent flows only in one direction. Alternating current moves back and forth, usually 50 or 60 cycles per second. It means that one pole is negative or positive 50 or 60 times per second.In electronics, other forms of electric current include the flow of electrons through resistors or through the vacuum in a vacuum tube, the flow of ions inside a battery or a neuron, and the flow of holes within a semiconductor.
What happens to the electric current when the wire is made smaller?
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
What is the relationship between the size of an electric current passing through a lenght of wire and its heating effect?
The higher the current, the more heat generated. Also, the smaller the diameter of the wire, the higher the heat. It is important to choose the correct amperage rating of the wire to prevent fires.Another AnswerThe work done by an electric current is the product of the square of that current, and the resistance of the conductor. The resulting heat depends upon the difference between the temperature of the conductor and that of the surrounding air. Remember, heat is defined as the transfer of energy between objects at different temperatures.
