In this problem, we have been given the following voltage regulator circuit.
00:05
And it has also been given that the power rating across the xenar diode, that is 400 millivort.
00:15
And here we have to determine the value of the load resistance, which will establish maximum power in the given xenadiod.
00:24
So as we can observe, the voltage across the xenad diode, that is 10 volt.
00:29
So we can probably compute the current which is flowing through the zina diode.
00:34
And we have the idea about the power across the zina diode.
00:38
And we know that power is the product of voltage times the current.
00:42
So if we get the current across the zina diode are flowing through the zina diode, that can be obtained by dividing power, which is 400 milliwatt divided by the voltage.
00:56
That's 10.
00:57
So when we divide this, we're going to get the value of current coming out to be 40 millie -amperes...
