Alright all of you wanna-be electrical engineers, it doesn't matter what side they go on. The same current flows through both elements no matter what order they are in. The reaction time is based on the magnitude of the combined impedance from the injector and resistor, along with the electro-mechanical work done by the coil's magnetic field. It has nothing to with something as trivial as element order. The same voltage drops across the two elements in both configurations.
How about some generalized equations.
V=IR, so I=(V/R). Follow?
Is (12/(5+7)) the same thing as (12/7+5)? If you got 1 for both equations, you're right. Now, I could work out the transient response too, but we wouldn't get too far into that exercise before the answer became evident.
This isn't an attack on anyone, just a general message. Don't try to pass off stuff you think you know as the truth. Keep it real!
