    How Does an Electric Field Propagate Through Wires?

    es1, thanks for the reply! ... there's still some gaps in my understanding ... say you have a 5V battery ... on the +ve terminal we have an excess of positive charge and on the -ve terminal we have a negative charge. in essence the battery acts as only a pump and does not provide any extra...

    How Does an Electric Field Propagate Through Wires?

    hi! Can anyone explain how an electric field propagates from one point to another? For example if i touch two 6ft wires to the ends of a 5V battery, i'll get 5V across the end of the wires after a propagation delay. How does the electric field (voltage) of the battery make it's way down to...

    Confused about voltage at electron level

    light_bulb, thanks! i was actually talking more about the electric field moving down the trace as a wave. If i were to visually depict the voltage on a trace what would a 3V line look in comparision to a 5V line? just more electrons? I didn't think electrons could just bunch up next to each...

    Question about return current in high speed design

    berkeman, thanks for the explanation ! just a couple of follow up questions to fill in the gaps in my understanding. 1. what exactly causes the inductance to rise when you move the return path away? 2. say you had a 2mA draw when the return path was under the trace. When you move it away do...

    Question about return current in high speed design

    I have a question about return currents. Now, all current needs to travel in a loop. so any charge that leaves a source must return to it (correct me if I'm wrong). usually on a high speed design the return current wants to travel right underneath the trace which is usually the ground plane...

    Confused about voltage at electron level

    Ok, so I've been struggling with understanding voltage down to the electron level. I know a voltage by itself has no meaning. We want a voltage difference. i.e. voltage diff between point A and B and that ground really has no meaning except as a reference. and i know that current is the movement...
