FWD Resistor Breakdown no switches

00:58:11

What makes these circuits different? Am I wrong in my calculation of parallel resistance and how this circuit is set up? Is the simulation off in some way? 

My assumption is after voltage drops at the 310ohm resistor it would have split evenly between the two 460ohm resister. 

The circuit on the bottom is supposed to be a simplified version of the top circuit. Any help is appreciated

In the first circuit, the last two resistors are in parallel. The first bottom 4.7k resistor is then in parallel with its resistor + the last two resistors. http://everycircuit.com/circuit/5980767283576832

Your absolutely right I see it now thanks I think I had a lapse in how I was breaking down the other parts of the circuit. It makes complete sense, a little embarrassing to have to be reminded of how to break down these circuits. Guess that’s what happens when you don’t use it for a while.

Hi @bcoop1990, you have confused yourself a little in the way you've redrawn the circuit. The right hand branch of the circuit should be the left hand 510 Ohm in series with the parallel combination of the right hand 510 Ohm and the right hand 4k7.

I've redrawn it here https://everycircuit.com/circuit/5221769252962304

Thanks for removing the s. First time I’ve ever provided a link - and I did it on my PC, forgetting to remove it.
