I'm confused about wheatstone bridges. I thought the balance condition was r1/r2 = r3/r4, and ive also seen it written as r1/r3 = r2/r4. Now looking at this i get why theres a voltage difference across the middle resistor, but how can the equations make sense then, if accordingly
r1 = 500
r2 = 1000
r3 = 500
r4 = 1000
so 500/1000 = 500/ 1000 or 500/500 = 1000/1000??
