In theory it means that in infinitely high current will flow through the conductor, as described by Ohm's law I=V/R. Theoretically you would then be able to power a submarine from a AAA battery.
In practice, it means that the maxim current that will flow is the maximum that your current source is able to provide. If a battery is rated a 8Ah, it means that it can safely supply 8A for a total of 1hr before it's flat. With a zero resistance it will supply an infinitely high current for an infinitely short period of time and then it will be flat.

"Theoretically" a AAA battery couldn't possibly power a submarine, regardless of the resistance of the propulsion system, as it takes a huge amount of energy to drive that submarine, and a AAA battery couldn't possibly provide that amount!!

∙ 13y agoZero resistance would be a perfect conductor where the electrons move freely without any losses. Such a conductor doesn't exist. By dropping temperature to near absolute zero very low resistances can be achieved.

What resistance does a superconductor have?
An ideal superconductor has exactly zero losses, thus resistance is zero.
What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
The resistance of earth wire is?
The recommended resistance that one should strive to obtain is zero.
Why the resistance of forward bias is equals to zero nd resistance of reverse bias is infinite?
the junction is conducting when forward biased, approaching zero resistancethe junction is nonconducting when reverse biased, approaching infinite resistanceneither is exactly zero or infinite
Does the current generates if there is no resistance in the circuit?
You can have current without resistance. You would just have zero voltage drop across that zero resistance.However, the question is very interesting, because if you really had zero resistance in the entire circuit, it would be impossible to have any voltage at all without generating an infinite current, so the answer in the theoretical case is no, you can have no current, nor voltage, if there is no resistance at any point in the circuit.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor has zero resistance.
What resistance does a superconductor have?
An ideal superconductor has exactly zero losses, thus resistance is zero.

If a multimeter reads zero on the ohm scale is this high or low resistance?
zero is low resistance
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Does a conductor have zero resistance?
No
When cooled this contains almost zero resistance?
Anything with the property of zero electrical resistance is called a super-conductor.
What would you expect if resistance of the fixed resistor was zero?
zero
An open fuse has a resistance of?
Zero. There is no resistance on an open fuse because there is no connection between the terminals on the fuse. I beg to differ There is INFINITE resistance in a BLOWN fuse... There is ZERO resistance in a GOOD fuse.
What does a super conducter do?
It has no (zero) resistance - thus current flows without losses.
What is resistance of an ideal ammeter?
ideal ammeter has zero internal resistance
Dc resistance of diode is a static resistance b dynamic resistance c high resistance d zero resistance?
B - Dynamic resistance
