Fuses have high resistivity because they are typically made of materials like copper, silver, or alloys which have inherently high resistivity. This property allows the fuse to generate heat when current flows through it, ultimately leading to melting and breaking the circuit in case of a fault. The high resistivity ensures that the fuse can handle the current without immediately melting under normal operating conditions.
What else can I help you with?
Is it true that a material with high resistivity is a good conductor?
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
What is the resistivity of deionized water and how does it compare to the resistivity of other types of water?
The resistivity of deionized water is high, meaning it is a good insulator. It is higher than the resistivity of tap water or seawater, which have more dissolved ions and conduct electricity better.
What is resistivity on what factor is depends?
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.
What is the resistivity of polyamide?
The resistivity of polyamide, commonly known as nylon, typically ranges from 10^12 to 10^14 ohm-cm. This means that polyamide is considered to be a good insulator due to its high resistivity.
What is the range of resistivity of insulator?
The resistivity of insulators typically ranges from 10^10 to 10^20 ohm-meter. This high resistivity makes insulators good at preventing the flow of electric current.
Do wires that have high resistivity have high conductivity also?
No. In fact it is the opposite. Conductivity is the reciprocal of resistivity so a high resistivity means low conductivity. peace.
Does high resistivity have a higher number or lower number?
High resistivity corresponds to a higher numerical value. In the context of materials, resistivity is a measure of how strongly a material opposes the flow of electric current; materials with high resistivity, like rubber or glass, have larger resistivity values compared to conductive materials like copper or aluminum, which have low resistivity values.
Is it true that a material with high resistivity is a good conductor?
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
A fuse will melt if the?
A fuse is made with the material which offers high resistivity. When a large amount of electric current passes through the fuse, heat above the melting point of fuse is produced. Hence, the fuse melts.
What is specific resistance and melting point of fuse?
low resistivity and low melting point.
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.
What is the resistivity of deionized water and how does it compare to the resistivity of other types of water?
The resistivity of deionized water is high, meaning it is a good insulator. It is higher than the resistivity of tap water or seawater, which have more dissolved ions and conduct electricity better.

Why is the resistivity of a potentiometer high?
Because you touch yourself at night.
What is the resistivity of polyamide?
The resistivity of polyamide, commonly known as nylon, typically ranges from 10^12 to 10^14 ohm-cm. This means that polyamide is considered to be a good insulator due to its high resistivity.
Is pyrite high resistivity?
Pyrite, also known as "fool's gold," has relatively low electrical resistivity compared to many other minerals. Its resistivity can vary based on its composition and impurities, but it typically conducts electricity better than insulating materials. Therefore, while it is not a conductor like metals, it is considered to have moderate conductivity, rather than high resistivity.
