What is the relationship between the length, material, and inductance of a wire?
The relationship between the length, material, and inductance of a wire is that the inductance of a wire increases with its length and the type of material it is made of. A longer wire and a wire made of a material with higher conductivity will have higher inductance.
What happened to the material when bent in electric wire?
When an electric wire is bent, the material comprising the wire undergoes deformation. The atoms within the material shift positions as the wire is bent, causing a change in its physical structure. This deformation can affect the wire's electrical conductivity and mechanical properties.
If the diameter of wire is double what is resestivity?
The resistivity of a material does not depend on the diameter of the wire. Resistivity is an intrinsic property of the material and is constant regardless of the wire's diameter.
How can the electricity pass through the rubber cover over the wire when a circuit is connected in parallel?
Electricity can pass through the rubber cover because rubber is actually a good insulator, meaning it doesn't conduct electricity. The electricity flows through the wire inside the rubber cover, which acts as a barrier to prevent the current from passing through the rubber material itself. In a parallel circuit, the current has multiple paths to take, so it bypasses the rubber covering and flows through the wire.
What kind of wire can be used to make a magnet?
A copper wire can be used to make an electromagnet by wrapping it around a magnetic core material such as iron. When an electric current flows through the wire, it creates a magnetic field around the wire, which magnetizes the core material.
