Question

A conductor is made in the form of a hollow cylinder with inner and outer radii a and b, respectively. It carries a current I, uniformly distributed over its cross section.

Answer 1

A conductor is made in the form of a hollow cylinder with inner and outer radii a and b, respectively. It carries a current I, uniformly distributed over its cross section. We are given that

• Inner radius,
• Outer radius,
• Current=I
• a.If r<a

Consider a loop of radius r where r<a

What is conductor?

A conductor is an object or kind of material that permits the movement of charge (electric current) in one or more directions. This term is used in both physics and electrical engineering. Metal-based materials are frequently used as electrical conductors. Negatively charged electrons, positively charged holes, and occasionally positive or negative ions flow to create electric current.

It is not essential for one charged particle to move from the component creating the current (the current source) to those consuming it for current to flow within a closed electrical circuit (the loads). Instead, the charged particle only needs to nuzzle its neighbor a limited number of times, and then the process repeats itself until a particle gets nuzzled into the consumer, generating electricity.
