Hello student, here the voltage across the zener diode will remain constant as long as the diode is 1.
00:10
So, the current through the resistor r, i r equals to v minus v z divided by r which is 12 minus 5 divided by 500.
00:26
So, this will be in the unit of ampere.
00:30
This is equal to 0 .014 ampere, this i r.
00:40
Now, i z current through the zener diode is i r into r l divided by r l plus r z.
00:56
So, this is equals to 0 .014.
01:05
Now, let us assume that when r l equals to 500 ohm, then i z equals to i r which is 0 .014 into 500, r l is 500 plus 500 plus r z is 40.
01:34
So, this is equals to 0 .0129 ampere.
01:41
So, the current through the resistor r l, i l is load current is i r minus i z.
01:58
So, which is equals to 0 .0011 ampere...
