Hi,
I need to find the potential between the node C (junction of R2, R3, and R4) and the ground.
This is a "basic electricity" problem (without using the node method or something else) but I have two problems.
Here's what I found:
let i1 (respectively i2, i3, i4) be the current through the resistor R1 (respectively R2, R3, R4)
but no current is passing through the battery V2, so by applying KVL to the left loop:
(that's my first problem: I hope it's "i1"...)
My second problem is: I have some intuition that "i4 = 0".
Is it because no current is passing through V2? so we would have:
And then, the final part of the solution:
Is it correct according to you?

Rich (BB code):
i1 = i2
KCL: i2 + i4 = i3
so: i1 + i4 = i3
Rich (BB code):
V1 = (R1 + R2 + R3) * i1
My second problem is: I have some intuition that "i4 = 0".
Is it because no current is passing through V2? so we would have:
Rich (BB code):
i3 = i(through V1) = i1 (???)
Rich (BB code):
i1 = i2 = i3
V(R3) = R3 * i3 = R3 * (V1 / (R1 + R2 + R3))
and V(C) = V(R3) + V2
