>>9403492Ideally and in most practical cases no. In reality there will be an extremely small propagation delay on the order of picoseconds or less for current to reach the resistors furthest from the voltage source (assuming they're spaced relatively close together like on a breadboard). It'll happen so quickly that most average oscilloscopes won't have the enough resolution in the timebase to even see the difference.
>Do people making circuits have to take into account the order of which components are powered?It depends. For some circuits it's not critical, for others it matters but even when it does it has nothing to do with how far away components are from one another. Some digital stuff has power on orders to ensure a device works properly. Some devices might use oven stabilized oscillators in which case the oven needs to turn on a heat up before an instrument can perform accurate measurements so power may not even be applied to any signal processing circuitry until the control loop doing the temperature sensing has determined the oven reached the right temp. Power components can have power on orders because of safety or other stuff. It really depends. There's no general rule, it's very application dependent.
