Hi, in this question we have four conditions that is d1 and d2 are off, then d1 is on, d2 is off, then we have d2 on, d1 off and then we have d1, d2 are off.
00:20
So, for an ideal condition that is for ideal diode, so when diode are forward biased then it acts as a perfect conductor, perfect conductor with zero resistance.
00:37
Then if it is reverse biased then it acts as a perfect insulator, so perfect insulator with zero current.
00:50
So, now considering the figure now d1 is, so d1 is, so both d1 and d2 are off condition, we have i is equal to zero ampere and b plus 2 will be equal to zero, so b will be minus 2 volts.

Then, so this is for first case.

In the second case we have, so in second case we have d1 is on but d2 is off...
