And this question, we are given the voltage on current values for micro wire. I'm not no down the points again, but provide a let's draw a graph. You would do this on a crafty and hence it would be much more, much better on more formal. I'm trying it roughly to scare. Now let's finish drawing a graph scale first. Now we want to draw a graph ofthe V vs so that when we did the slope we buy, tell Dobby build, I would be our assistance. No, we need to choose proper. Yet we know that all data the voltage goes from Syria. The current goes from 0.5 ampere 24 ampere on the whole discourse from 1.94 for 15 0.5 Do. Let's track down the rest of them do. It's one ampere and two amperes on the Although it has been 3.8 and 7.76 now, it's an important skill to choose your unit's properly when you draw any glass, as you see that the current goes from 0.5 before a proper unit charge would be 012 and three and four, whereas for hold it because it calls from almost to toe almost 16 properly. Choice would be 16 12 84 and zero. This way all of her points will be within this. Great. Now the units here, our world on the messier amperes. Mind you, mother, you know this was simply we simply dirty points now for syrup on five ampere which is about here We see that the voltage is almost fooled. Just have off this grid Hence this is almost a point when you do it, Ana gas it or even better on the computer. This will be much better and more exact. Let's use a different color. This is our first point now for second point. It is at one AM Pierre. It's almost fore ward, which is this for the third point at two AM peers, it is almost eight fold. So it's almost here. And for the last point, it is that at four AM Pierre, it's almost 16 world which is almost here. I was there a line through it are even better. Do it with a scale on a graph or do a fit on a computer. It will be much better, but you can see that they're almost on a straight line, which takes us to the second part. It looks like it always the onslaught. A better way to take it is to find out we to buy even aunt compare it with a two by one. Now if we equal toe I r on our physical Toby by eye, then for the same resistance we expect we buy I to be the same on. Hence we expect we to buy everyone to be equal toe. Edouard, I won and we can see the 3.84 by 1.4 is too, which is the same as one by 0.5 and two boys are upon five is four, which is the same as 7.76 by 1.9 for and it is eight for the last case on. If you do a fit on a computer, you'll see that all of the line, all of the points, like exactly on the straight line off your friends, which is how you know the onslaught is obeyed in this case Now for party, we want to find the resistance cells, which is simply Delta V vital that I so we can simply take the lot. The first data data point with the last data point. Dobby is 15.52 World minus 1.9 forward, divided by Hilda is for ampere minus 0.5 ampere which stands out away 3.88 Oh!
