    Graph Slope
In summary, using a higher value resistor would result in a downward curve in the slope of the graph for current vs. voltage. If the resistor overheats, it would not be possible to verify Ohm's Law. To make Ohm's Law useful for graphing, it can be rearranged to V = IR, where V is voltage, I is current, and R is resistance.

Homework Statement



What would happen to the slope of the graph- Current Vs. Voltage if a higher value resistor was used?

Homework Equations



Slope is the Resistance R. This experiement was intended to verify Ohm's Law; however, can you verify Ohm's Law if the resistor overheated in the experiment? How would you rearrange Ohm's Law equation to make it useful to graph y=mx?


The Attempt at a Solution



Maybe there would be a downward curve in the slope because a higher value resistor would decrease the flow of current?

This would mean that the slope would decrease. If the resistor overheats in the experiment, then it would be impossible to verify Ohm's Law because the resistance would change. If Ohm's law is rearranged to make it useful to graph y=mx, then it becomes V = IR, or Voltage (V) equals Current (I) multiplied by Resistance (R).
 

What would happen to the slope of the graph if the x-values increase?

If the x-values increase, the slope of the graph will also increase. This is because the slope of a line is determined by the change in y-values over the change in x-values. So, as the x-values increase, the change in y-values will also increase, resulting in a steeper slope.

What effect does a positive slope have on the graph?

A positive slope indicates that the graph is increasing from left to right. This means that as the x-values increase, the y-values also increase. In other words, the dependent variable is increasing as the independent variable increases. This is often seen in graphs that represent direct relationships between two variables.

Will the slope of the graph change if the y-values are multiplied by a constant?

Yes, the slope of the graph will change if the y-values are multiplied by a constant. This is because the slope is calculated by dividing the change in y-values by the change in x-values. When the y-values are multiplied by a constant, the change in y-values will also be multiplied by that constant, resulting in a different slope.

What would happen to the slope of the graph if the y-values decrease?

If the y-values decrease, the slope of the graph will also decrease. This is because the slope is determined by the change in y-values over the change in x-values. So, as the y-values decrease, the change in y-values will also decrease, resulting in a flatter slope.

How does a negative slope affect the graph?

A negative slope indicates that the graph is decreasing from left to right. This means that as the x-values increase, the y-values decrease. In other words, the dependent variable is decreasing as the independent variable increases. This is often seen in graphs that represent inverse relationships between two variables.
