Question number 14.
00:03
The graphs given below show the relationship between potential difference and current for four different resistors.
00:11
Which of these resistors has the greatest resistance? okay.
00:14
Let's check our graph here.
00:17
So we know that in the y -axis, we are given the current.
00:22
And the voltage is plotted along the x -axis.
00:26
Okay.
00:27
So to help us answer the question, we will use the two concepts.
00:31
One is omslaw, which is the fundamental law in analyzing simple circuits.
00:38
And the other one is, of course, the concept of the slope of a line.
00:43
So oms law will tell us that the ratio of voltage or potential difference to current is equivalent to resistance.
00:52
But when we get the slope of the given graph, okay, let's take a look at the slope here.
00:57
We actually have here the change in the quantity in the y axis that would be the current divided by the change in the quantity along the x which is voltage so this is now the slope of the given line which is obviously the reciprocal of resistance so if we get the current rate current voltage ratio this is actually the reciprocal of resistance and this is equivalent to what we call conductivity...
