Okay, so now what we're going to measure some current. And what I've done here is I put our three little nine volt batteries in series ating just as we did originally, so let's just for the fun of it, let's measure the voltage. So this is I'm gonna walk, plug my green red meter lead to that, which is positive. And here's my negative over here with my green lead, and I'm going to plug guy or clip that on. All right, so here's my black meter lead, and here's my negative terminal, this battery and if you can See, this, this clip lead here is attached to the probe. And here's my positive right there and that's attached to the white lead or the red meter lead there.

I'm going to turn my meter on. Whoops, one more went up too quick. One down. Okay, I'm going to select DC volts. And there we go. 29.3 volts.

Okay, so now I'm going to walk, turn my meter off. And now we're going to place my 510 ohm resistor right there, right here in series with the meter because we measure current in series, so I'm gonna take this off The white side and I'm going to clip it onto one side of the meter. Then I'm going to get a another clip lead. And I'm going to clip Li the other side of the resistor. And then I'm going to clip this on to my red meter lead. But before we do that, all right, I'm going to put that there like this.

I'm going to turn my meter on to current and see one more milli ampere. I'm on milliamp hours. And now I'm going to clip that on. Make sure I'm on DC I didn't make sure that but I am now and I'm reading about 53 milliamp hours now. That resistor is getting warm because that's radiant above, that's a quarter watt resistor, I'm sure there's more than a quarter watt of power dissipating it. So let's, let's measure the temperature on now.

So I'm going to turn this off, disconnect this. See it's smoking a little bit, I don't know if you can see it. And I'm gonna, I'm gonna put my temperature probe so I'm going to disconnect my regular meter leads here. Hi, and I am going to connect my temperature probe. And we're going to measure the temperature on that. Okay, just like we did before, but that looks like it's really cooking here.

So let's see what It goes on. And before I connect that, I gotta go to temp. And I'm going to leave it on Fahrenheit. I it so it's cooling down. So let me see here, we gotta, we got to connect this resistor. Alright, so I think if I just clip these two together, actually, let me let me take this green lead off, because we don't need this green lead.

And if you can see, I'm going to take this and I'm going to connect it there. Alright, and then we're going to measure temperature. So let me do that. Now we've got current flows. So let's see what the temperature is on there. And it's cooking 212 degrees Fahrenheit is boiling.

So that was going up. So let's see what happens. If I disconnected it, it should start going down. It got so hot that my, my temperature probe is kind of sticking to it, but it's cooling down. All right, and this is why we need to calculate our wattage ratings of our components because we can destroy them like we did there. I didn't think I just took that out.

All right, um, I'm going to stop the video now and we'll pick it up with the two batteries in series in a minute. Okay, now we've got two batteries in series. I've replaced the 510 home here, but when in the last I've, I've held on to that resistor. So when we go to measure resistances in the next section and we do a lab on that, we're going to measure the resistance of that. Okay? So, let's up, let's check and make sure that we've got voltage.

So again, I'm turning my meter on to voltage. All right, I'm gonna hit select, whoops, no, I'm not in voltage. There we go. I'm going to hit select. Okay, and it's on auto. So now I'm going to take my two meter leads, and I'm going to go across my battery, and we've got two so let's see, we get Okay, we get 19.7.

Okay, so now I'm gonna do that place my leads down. Got one clip lead here. That's going to my positive meter lead. And now I'm going to clip another clip lead on the other side of the resistor. And now I'm going to my negative, I mean, I'm sorry, going to my positive meter lead. Right now what I'm going to do is I'm going to adjust my get on my current scale.

So I'm on my milli ampere scale. And instead of putting a clip Li this time, what I can do is I can just go on my battery and that's because I'm on AC. Whoops. Now I'm reading 36 points. For milliamp hours, which sounds about right, all right, because we've got a 510 ohm resistor in there. All right.

All right. So now just to speed things up, I'm going to put that down. I'm going to leave my media lead there. I'm going to take this battery out. And now we're going to measure nine volts because we have a nine volt battery. So let's see what we get.

Now I half which would make sense because I have half the battery voltage, but my resistance stayed the same. All right, now if I want and double check my battery voltage, I can go over here. All right, make sure I'm on DC volts. Take my meter lead here. This connect it right there. And we should see around nine volts, which we do 9.88.

All right. So now what we're going to do is we're going to do it with we're going to go through the same exercise just to say we did with a 10 K, and then 100 K. So I'm going to stop the video now and we're gonna do it with those two resistors. Okay, we're gonna go through the same thing here now with a with a 10 K resistor right there. All right, so I've already set up my, I've already set up my, my, my pre batteries. Alright, let's just go through it. Let's measure the battery voltage.

All right, make sure I'm on DC. I and again, I'm gonna pick up the pace here because it's kind of redundant, but I've got them in series ating. And then we go. Alright, so now I want to measure my current, we know that the resistor has to be in series with that. Alright, here's my two probes. So now what am I going to do?

Well, I'm going to take my Mita lead and I'm going to go to my milliamp hour scale, which is right there. I'm going to make sure that I'm on DC. All right, I'm going to take one side of my resistor clip, clip a lead on that. All right, and I'm going to the positive terminal of the battery. Here we go. All right.

And now I'm going to get another meter lead. And we'll get a yellow one here because yellows pretty and I'm going to clip him Here I am, and I am going to click on my red meter lead right here. All right, and just like I did before, I'm going to take my black mirror lead, and I'm going to touch the other side of the resistor. And look at what I get. I get almost 3 million campers, I get 2.9 million campers. All right, let me do that again.

Let me so I'm measuring 2.96 milliamp hours or close to three. And I've got three nine volt batteries in series and that's a 10 K resistor. So Let's do this. Okay, I can let's disconnect one. Alrighty. And I'm going to disconnect.

Let's see. Yep, we're good. We're good. We're good. So I'm going to disconnect this one. And that take that off.

And now what should I read? I should read about a third last. All right. So it should be about two. All right. And now let's do this.

It should be about one. A Look at that, huh? One milli ampere. All right. So here we go. So now what I'm going to do is I'm stop the video and we're going to proceed In the hundred k
