Hi, the problem is attached and i'm trying to solve it and despite me doing circuit theory for the past weeks, this problem has me stumped.
I want to calculate the current I over R1 and R2.
Regarding R2 using the loop current method.
Why won't U3 give any current to R2? This has me stumped.
Taking the U2 in a loop counter-clock I'd get:
U2-I2*R2 + U3*R2 = 0
Is it so easy that the current on the negative side of U3 is zero because we have it grounded there? So:
U2-I2*R2 +0*R2 = 0 ?
Thx in advance!
