Zero-ohm resistors are used mostly in printed circuit boards in place of jumper wires.
They have no to little resistance, so they are used to just connect sections of a circuit. The automatic insertion machines that create PCBs are not adept at connecting jumper wires, but can place zero-ohm resistors easily on the board.
A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.
Why would you buy something that does absolutely nothing? If you need a "zero ohm resistor", just don't connect any resistor at all.Why would you buy something that does absolutely nothing?

A zero ohm resistor is a piece of wire with a resistor body. It is essentially a jumper. It is useful when a jumper is need on a printed circuit board that is assembled by automated machinery, because the automated machinery can handle resistor insertion far easier than a jumper wire. The color coding on a zero ohm resistor is one single black band.
No, an open resistor has a value of infinity. An open resistor typically will measure over 900 Megohms. A zero ohm resistor is exactly that, and will measure zero ohms. They are typically surface-mount devices.
The current would be about 20 volts.

No, a 2.2k ohm resistor and a 220 ohm resistor are not the same resistance. The "k" in 2.2k ohm stands for "kilo," which represents a multiplier of 1000. Therefore, a 2.2k ohm resistor is equivalent to 2200 ohms, while a 220 ohm resistor is simply 220 ohms. The difference in resistance values is a factor of 10 due to the kilo prefix.
A: Extremely important since at the level there is infinite current available at zero volts, In reality it can never be ac hived but it can be assumed for consideration Each piece of hookup wire can be thought of as a zero-ohm resistor. In fact even the hookup wire has resistance but it's so small it it can be neglected.
I don't see a question. Please clarify if you want an answer.
