Hi, here in this given problem this is a network of pn junction diodes and resistors.
00:15
This is the diode d1, resistance r1, another pn junction diode, d2 and another resistance r2 here.
00:44
And a battery having an emfe value of this emf is 17 volt resistance r1 this is 2 kilo ome or we can say this is 2 ,000 ome and resistance r2 this is 3 kilo ome means this is 3 ,000 om.
01:19
Here this is the current i1 passing through the resistance r1 and a current i d2 passing through the diode d2 as both of the diodes are forward biased p crystal is joined towards the positive terminal of the cell so both of them are forward biased so so they will offer zero resistance.
02:16
Means if you look at this r1 here, this r1 will be short circuited by this d2.
02:35
So there is only r2 in the circuit.
02:52
Therefore, equivalent circuit looks like diode d1 that is short -circuited, diode d2 that is also short -circuited...
