Short version: Yep. That''s what a short circuit is. Typically, you will get current to flow as long as it has a path with finite resistance (even zero), a voltage difference, and a supply of charge carriers (e.g., electrons). If there really were no resistance in the circuit, the ...
22.9: Magnetic Fields Produced by Currents
Such a large current through 1000 loops squeezed into a meter''s length would produce significant heating. Higher currents can be achieved by using superconducting wires, although this is expensive. There is an upper limit to the current, since the superconducting state is disrupted by very large magnetic fields.
electric circuits
There is no current flowing from its positive to its negative end because both the air and the internal insulation of the battery are preventing current flow. Back to your example. Let''s say you have an wire connected to a positive and negative end of a battery. The current will flow through the wire to the negative end of the battery.

On two points of the wire before the current hits any resistors, I attach the readers of a voltmeter. Since there is no resistance, and the formula for voltage is V = IR, does this mean that the voltage would read zero in between those two points?

One way to look at this is to think of the flow of current through a wire similar to water flowing in a pipe. (I actually detest this analogy, but it''s simple enough.) If you measure the flow at two different points in the same pipe, the readings will be the same, as long as you are looking at the volume of water passing per unit time, in ...

The current flowing from the voltage source in Figure (PageIndex{4}) depends on the voltage supplied by the voltage source and the equivalent resistance of the circuit.

electrostatics
A wire is essentially a long, thin conductor yet electrons do indeed flow so there must be an electric field. Correct. For example, if there is a steady current through a (non-ideal) conductor, there is a constant electric field within the conductor. Note that, for an ideal conductor, no electric field is needed to sustain a steady current.

$begingroup$ As the responses indicate, current will flow through all paths, with more current flowing through the lower-resistance paths. But often when people say "electricity takes the path of least resistance," they''re discussing a circumstance where the paths differ dramatically in resistance, such as a wet hand vs. an air gap.
