Dec 18, 2016 at 9:53 comment added user399511 Where ever there is a potential difference, There is Electric Field.
Dec 18, 2016 at 8:55 comment added MrAP Is electric field present across the short-circuit?
Dec 17, 2016 at 4:57 comment added user399511 In a wire electron ar in random motion. Such that If we place an Area A normal to the wire, the number of electrons crossing the A,say, from left to right will be equal to the number of electrons crossing A from right to left. Hence there is no current in the wire. For current to flow, We must apply electric field across the wire so that free charges gets accelerated as per F=qE. Hence, There will be some number of electron crossing A in the direction opposite to the applied Electric Field Therefore, We get current.
Dec 16, 2016 at 19:17 comment added MrAP I cannot reconcile the opposing facts. You agree that current will not flow along 1-4 and 2-5 but the answers say that the short circuit draws a large amount of current.
Dec 16, 2016 at 17:31 comment added user399511 Read the answers given to that question ( link of which you provide in the comment). They have explained the rest.
Dec 16, 2016 at 17:12 comment added MrAP But 1-4,2-5 are short circuits and this article says that all current flows through it:physics.stackexchange.com/questions/74368/…
Dec 16, 2016 at 16:28 comment added user399511 No. You have read wrong. Current does not follow least resistive path. If it were to, in in parallel combination of resistor all the current should flow through the resistor of least resistance. Correct is: Current flow through the shortest path across which there is a potential drop.
Dec 16, 2016 at 16:24 comment added MrAP I have another question in addition to the above. I have read that current chooses the least resistive path and according to this principle all the current should flow along the blank wire. What do you think?
Dec 16, 2016 at 16:23 comment added user399511 Yes. Because for current to flow through 1-4 and 2-5 there should be potential drop.
Dec 16, 2016 at 16:21 comment added MrAP You mean that charge will not flow along 1-4 and 2-5 but 1-2,2-3,3-4,4-5?
