- The thinner the wire, the bigger its resistance. You must use thick wire to carry a large current, or the wire gets too hot and melts (like a fuse). The relationship between resistance and thickness is not straightforward.Halving the thickness of a wire does not double the resistance. Compare this with the relationship between a wire's resistance and its length.he cross-sectional area is what you get when you cut through the wire, at right angles to its length, and look at the cut surface. If the wire is round, the cross-section is a flat circle and the area is πr2.

resistance and ohm law This obstruction is called electrical resistance. The longer the conductor higher the resistance. The smaller its area the higher its resistance; Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Resistance is a measure of how much an object opposes the passage of electrons. The unit of electrical resistance is the ohm and it is represented by ω. Every material has Resistance. Copper has a low resistance and wood has a high resistance.

Electrical resistance and conductance The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction.

Electrical Resistance and Ohmâs Law Questions. 1. As the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to voltage, the data should be in a straight line and it should go through zero.ypothesis. The graph of potential difference versus current for a resistor should result in a linear plot, in accordance with the equation R = V / I. To extract even more from this equation, the slope of said linear plot will be equal to the resistance.

Electrical resistivity and conductivity The SI unit of electrical resistivity is the ohm-metre (ω⋅m). As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 ω, then the resistivity of the material is 1 ω⋅m.

Factors that affect the resistance of a wire Factors that affect the resistance of a wire. The resistance of an object is a measure of the how reluctant current is to flow through that object. Current only flows through a component of a circuit if a potential difference (voltage) is put across it. The bigger the potential difference across its ends the bigger the current flow.

In ohms what is the electrical resistance of water? Resistance is calculated by (resistivity)*(length)/(cross sectional area). First consider a wire conductor. Electrical resistivity is a property of the substance (it usually will vary with temperature). The thicker a wire is (larger cross sectional area) will lower the resistance.

Electrical resistivity and conductivity For specific applications in electrical elements, see Electrical resistance and conductance. Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current.

- Its basically the literal amount of resistance the current encounters getting from point A(the positive connection) to point B(the negative). Thicker wire means less resistance because it allows more current through at any given time, and thinner wire is the opposite because it allows less.

How time is related with resistance and capacitance? Time is related to resistance and capacitance when there is a change in current. This happens when a switch is opened or closed, or a battery is connected or disconnected, etc... *note: C always=q/V, so the actual capacitance doesn't change.
