A conductor carrying a single electron directly in the centre meets a junction in which the the resistance are equal and are of 1 ohm, using knowledge of the various circuit characteristic laws, explain what would be the the potential across the branches


since from my knowledge since the resistance is equal in both channels is the likely hood of the electron passing through one of them is 50 50 or just that no current will flow, I am a bit confused
 
Physics news on Phys.org
Current in conductors is not the ordered motion of single electrons. If that is the exact problem statement, it does not make sense.
 
Also note that it is impossible to say which wire the electron will go through, regardless of the resistance.
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
