What does the resistance vs length graph show in terms of the relationship between resistance and length?

The resistance vs length graph shows that there is a direct relationship between resistance and length. As the length of the material increases, the resistance also increases.


Why is a graph of voltage against current for a filament bulb curved?

Because as current increases, heat increases and therefore resistance increases. Since resistance is the gradient of the graph, the gradient will increase and therefore the graph will curve. (The filament in the bulb is an non-ohmic conductor; its resistance is only constant at a constant temperature.)Another AnswerIncandescent lamp filaments are manufactured from tungsten. Tungsten is classified as 'non-ohmic' or 'non-linear', which means that (in common with most materials, in fact) it does not obey Ohm's Law. For a material to obey Ohm's Law, the ratio of voltage to current (i.e. its resistance) must remain constant for variations in voltage -as you have discovered, tungsten doesn't do this, producing a curve, rather than a linear, graph. As the original answer indicates, the temperature coefficient of resistance of tungsten in such that, as it gets warmer, its resistance increases.Those few materials that do obey Ohm's Law are called 'ohmic' or 'linear' materials.


How do you find resistance by a graph?

To find resistance from a graph of voltage vs. current, you can calculate the slope of the graph. Resistance is equal to the slope, so you can divide the voltage by the current to determine the resistance. The unit of resistance is ohms (Ω).


What does the slope of mass vs volume graph represent?

The slope of a mass vs volume graph represents the density of the material being measured. Density is a measure of how much mass is contained in a given volume of a material. The steeper the slope, the higher the density of the material.


What does the slope of a graph potential difference vs current represent?

The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.

Graph of resistance of filament lamp against potential difference?

As potential difference increases in a filament lamp, resistance also increases due to an increase in temperature. The relationship between resistance and potential difference in a filament lamp is non-linear due to the temperature-dependent nature of resistance in the filament material. At low voltages, the resistance is relatively low, but as the temperature of the filament increases with higher voltages, the resistance also increases.


Why is the resistance vs current graph is not linear?

resitance is inversly proportional to current when (v) is kept constant <><><><><> Because resistance is a function of temperature.

In a graph showing temperature change of material over timetemperature change is the?

In a graph showing temperature change of a material over time, the x-axis typically represents time while the y-axis represents temperature. The slope of the line indicates the rate of temperature change, with a steeper slope representing a faster change in temperature. The point at which the line intersects the x-axis denotes the initial temperature of the material.

What is the basic principle of thermometer?

Resistance of a material would depend on the temperature. So drawing a graph with temperature along x axis and its resistance along y axis we could almost a straight line or curve. Then right knowing the resistance at some unknown temperature we can find the temperature right from the garph.
