All right, hello, in this question we're asked to determine if each of these components is supplying or drawing power and figure out how much power it is supplying.
00:09
So first off, we know that power is going to be our voltage times our current.
00:13
We have all our voltages and all our currents, so we can go ahead and figure out what the power for each of these is going to be.
00:20
So let's start with source one here.
00:22
The way that we determine if it's supplying power or absorbing power is it has to do with what direction the current is going relative to the voltage.
00:31
So if we have a current such going in the positive end and out the negative end, that is absorbing power.
00:39
So this is a resistor r.
00:42
So two, we're going to be absorbing because we have the current going in the positive terminal and out the negative terminal.
00:49
For one, we'll notice we have it the other way.
00:51
We have the current going out of the positive terminal.
00:54
So that is going to be providing power.
00:57
And then let's go ahead and just do that for the rest of them.
01:01
So for three, we're going in the positive terminal out the negative, so that's going to be absorbing...
