Both the diodes are in on state and in this condition the voltage drop on them is $V_{d} \sim .7 V$ no matter which is the current...Determine the voltage with respect to the ground at each point in figure. Assume the practical model.

I don't understand. the question is asking for the voltage with respect to the ground.

Let's start with point A.I don't understand. the question is asking for the voltage with respect to the ground.

There is a voltage source between ground and point A.

Its voltage is 25 V.

Therefore the voltage at point A is +25 V.

but i don't know how to determine the voltage at point c.

Good!point B is 24.3v. because the voltage drop across the diode is 0.7v so 25-0.7v=24.3 v

Let's do point D first then...but i don't know how to determine the voltage at point c.

There is a voltage source between ground and point D that determines its voltage.but how?
