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.

A fuse in a circuit is meant to burn out first if there is a short circuit. Should a fuse have a higher or lower resistance than the wire in the rest of the circuit?
The way current (series) fuses are designed and used, they are meant to overheat and blow and cause an open circuit if the current flow through these goes above the rated value. The resistance value typically is slightly higher than the wiring and adds marginal value of series resistance to the overall circuitry. The material characteristics of fuse ensure that at regular nominal current flow the fuse does not overheat, but when larger than expected current flows it overheats, melts (or gives very high resistance/open in a resettable fuse)and causes circuit to open.
Why is there resistance between the line and neutral of a receptacle?
The source is finite. Any real world power source is finite. You will see the same thing with a battery, for example (the battery has internal resistance). If you have no voltage at that recepticle, the resistance should approach infinite due to an open circuit (open breaker, fuse, broken conductor, etc.).

How do you know if fuse is blown on Audi A4 1999?
Check each fuse with a continuity tester - Set to OHM's Remove each fuse and connect leads to fuse - a good fuse with show continuity "0" resistance while a bad fuse will show "Infinity" resistance
What is the resistance of a blown fuse?
Infinite...a blown fuse is an 'open' in electronics terms. Infinite resistance.It will not read zero on a digital multimeter, it will read as a maximum resistance.A fuse, when good, has zero (practically speaking) resistance. When it blows, it has infinite resistance, thus on a multimeter it will provide a high reading.... When an analogue (not digital) multi-meter is set to ohms it will read zero when blown. If you touch both leads off the meter it will read full scale. if the leads are NOT touching the meter will read zero. so if your fuse is blown it will act like the leads are not touching because it is blown. It is good practice not to touch the exposed lead ends or the fuse under test as the resistance of your body can give a false reading.The ohm scale on an analog multimeter is reversed...when the meter is at the far left, what you might think is zero, it is indicating infinite resistance. When you try and determine the resistance of a fuse that is blown, the meter will not move from the left side of the scale. That is not zero resistance. That is infinite resistance.
Where is the fuse for the cigarette lighter in the Peugeot 4007?
behind the glove compartment on the passenger side. Open and unclip at each side and slide the resistance piston on the left hand side off its mounting. The fuse box sits behind
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 ()
What restricts the flow of energy?
You can change current by altering potential difference or resistance... But assuming the voltage is constant, the resistance of the circuit restricts the flow of electrical current.
What is the resistance when switch is open?
Nothing will happen to the resistance of the circuit. However, with the switch open, it will be 'seen' as having infinite resistance from the supply side.
Does a fuse have a low resistance?
Yes, fuses have a low resistance in order to not dominate the consumption of the circuit's power, such that the desired appliance wired in series with the fuse consumes the bulk of the power.
An open circuit has an infinate resistance?
There is no such a thing as infinite resistance but it could be a very high resistance.
