Can current propagate through a wire in both directions at the same time?

[gmeat]

Try to put amp meter on one of the battery positive and see if disconnecting other battery can show measureable change of current in the battery. Maybe using lamp or other static load to get stable measurement.

Try to lengthen the colliding part much much longer. maybe with coil or something.

Hi Sucahyo,


I did try putting an amp meter between the positive terminal and noticed a small amp increase which went from 1.42 amps to 1.48 amps when hooking up the second battery and the lights got slightly brighter. I also added a coil in place of the bridge and replaced the motors with 2 - 12 volt light bulbs that draw roughly 1.5 amps.I noticed that there was no amps measured across the bridge coil of the circuit as opposed to the motors where there was a reading and also there was no magnetic field present in the coil as there was with the motors.so I have to wonder if maybe it does'nt work the way I thought .I'm not sure what to make of all this yet.Thx for the ideas

I tested the circuit using 12v 50 ma bulbs with a dc motor as the as the apparent cross point. the bulbs were not affected as i connected and disconnected the motor. i metered the voltage between the two negatives and found it to be identical to the difference in potential of the two batteries. My question is how would if it behave differently if the bulbs were replaced with a choke. potentially even a jewel thief type circuit

Hi Redeagle,


I like your idea about the motor acting as the bridge and I'll have to try that out.You also mentioned other avenues to explore.Thx for your input to this thread .

By replacing light bulbs with switching mechananisms you can use a motor coil as the bridge. and connect a BR to the motor coil for receiving output.

Why use four transistors for a bipolar circuit when two will do the trick. additional generator coils can be used to generate power back to the input batteries for longer runtimes and the spike can be sent to a third battery for charging.

Sounds like a plan to me.

Addition: if you try this make sure the motor coil will not self oscillate and that the the two switches cannot close at the same time... if that happens it will short

Hi Everyone,


I just want to say to everyone that this circuit is a strange one to say the least, Although it appears to look as if it runs in series I'm not gonna budge that it's actually not in series.I just hope that maybe the more experienced electronics guys can better explain to me why the coil has a magnetic field in it but yet if I replace it with anything but a coil It wont light a lightbulb or turn a motor and I know that there is current in the coil but yet it cant be tapped .

Motors unlike light bulbs do not draw a constant stream of current. Also if the batteries weren't at the same voltage there would have been a potential difference at that point.

My conclusion: The circuit as presented will behave as a series circuit in most cases. Noted exceptions are inbalances in either load or potential.

DC motors carry a varying impedance to the electricity flowing through them do to the variance in Counter EMF as the motor turns. It is highly unlikely that the motors would syncronize themselves

Hi Guys,


One more observation is if you take the 2 negative leads and switch positions in the diagram I showed,I noticed that the amp draw through the bridge/crossover coil part of the circuit becomes additive and in my case with the 2 motors where 1 uses roughly 420 milliamps and the other uses 1.7 amps,I measured 2.1 amps through the Bridge/crossover coil.Not sure that this means anything or not but figured I'd mention it.

Thanks for the experiment . The purposes of using lamp is to reduce chance of motor EMF ruining measurement. Maybe with motor there is HV that help? current running in opposite direction since coil collapse current is reversed.

If by using lamp there is no current or magnetism in bridge coil when both circuit loop running then two opposite current can coexist. Maybe the coil capacity is big enough for both. Kind of two ship with opposite direction at opensea.

Hi Everyone,


One final thought before I call it a night is that I was able to run 1 half of the circuit on 24 volts and the motor sped up while the other motor stayed at the same speed so I'll say that that's a pretty strong indication to me that the circuit is not running in series.Thx for all the good replies to everyone that responded in this thread.

Use 12v bulbs and batteries.
Put 2-12v bulbs in series at the crossover.
Are the 4 bulbs the same brightness?
