When a wire is cut in a circuit, a gap is made and the current can no longer circulate, known as an open circuit.
When 2 parts of a circuit touch, that shouldn't, for example - a wire comes loose and comes into contact with another part of the circuit, its shortening the route of the current in the circuit. So its a short circuit. When this happens 99.9% of the time the result will be a spike in amp's, so tripping any circuit protection, MCB's, fuses.
A good example of a common short circuit is faulty windings on a 3-phase electric motor. If the resin separating the windings becomes damaged it can cause 2 or even 3 of the motors phases to come into contact causing the motors overload protection to trip.
Generically, it's an 'overcurrent'; specifically, it's a 'short-circuit current'.
An open circuit or a short-circuit (if that circuit is complete).
Your original question was in two parts:1.) How many ohms in an open circuit? Infinite ohms (the meter will show no measurement).2.) How many ohms in a short circuit? 0 ohms. There would be no measurable ohms as there would be no resistance in the altered circuit.
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
A short circuit is what usually causes a switchboard explosion.

Short term loans come in various lengths and each length can be meant for a different customer. Their lengths can range from a few months to many years.
A short circuit refers to an unintended connection between two points in an electrical circuit that bypasses the intended load. This can result in excessive current flow and can cause damage to the circuit components.
trends or passing phases, popular for a short time
The long term goals of a business are the aims and the objectives are the short term steps you take to get there.
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
A: FUSES are very good for short circuit protection. On the other hand a short over current may not make the fuse to blow since it requires heat caused by the current to blow. There are fuses that are meant to blow fast and some fuses are designed to blow slow depending on the circuit requirement
Not chaotic behavior; a tendency to overcome bias (unpredictable short term)
Short circuiting means providing a low resistive path, diverting maximum current away from where it was intended to go.
Shunting of a circuit is the electrical terminology for bypassing a circuit.
