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.

What is a fuse wire characterized by?
Low resistance and low melting point by "justquikr.com"
What is specific resistance and melting point of fuse?
low resistivity and low melting point.
What are the properties of a fuse wire?
It has high specific resistance and low melting point.........
Is fuse wire characterized by high resistance and high melting point?
Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
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.
Why can not copper wire be used as a fuse wire?
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
Does plastic have low resistance?
yes, it does have low resistance
What material is used to make a fuse wire?
The material suitable for making a fuse wire should have a low melting pt. so that it can easily melt and cut off the flow of current and save the electrical appliance...
Does the material used for a fuse wire need to have a low or a high melting point - a low or high ductility - a low or high resistivity?
The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor. As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
What will happen if ammeter is put across a resistance in a circuit?
Maybe blow the fuse or burn out the wiring. An ammeter has an extremely low resistance. connecting it across the resistance causes the resulting parallel resistance to be slightly lower than the resistance of the ammeter 1/Rt = 1/R + 1/R(ammeter)
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
