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.

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.
How much resistance in blown fuse?
INFINITE RESISTANCE Like taking your meter and holding the probes an inch apart in th air.
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
How to replace a blown brake light fuse?
Remove the blown fuse. Replace it with a new fuse.
What do you do when you've blown a fuse?
A fuse is a deliberate weak link which will be blown if there is a power overload. When you blow a fuse, take the blown fuse out and throw it away as you would a blown light bulb, and replace it with another fuse of the same type. * In the old-timey fuse boxes a penny could be substituted for a fuse, but a penny is too strong to be blown, and the next overload will burn the house down.
When the wire or foil strip inside a fuse melts what is it called?
It is called a blown fuse.
