Hi there, so for this problem, we are told that a center diode, it's if it's a constant voltage that is given, and that constant voltage is equal to 5 .6 bolts, and for currents greater than five times the need current.
00:22
So the current, let's call this the current i seed a, is, you know, seat case, sorry, seat k, is equal to 1 milanpers.
00:43
So the center is to be used in the design of a shunk regulator fat from a 15 balls supplies.
00:54
15 balls supply.
00:57
And the load current varies over a range from 0mmper to a value of a ampers.
01:14
Now find a suitable value for the resistor r.
01:20
So the question is, what is the maximum power dissipation of the senior diode? so we start by knowing that the minimum center current as the problem state should be five times the current given for the need current.
01:42
So that will be just simply five times the one milliampers given.
01:47
So that will be five miliampers.
01:51
Now since the load current can be as large as 15 mili ampers.
01:58
Um, um, pairs.
02:00
A senior current of 5 million perts is available...
