Explanation

The meaning of the steady current is that the current is uniform all over the conductor.

Therefore, it will be constant throughout the length of the conductor.

Hence, current (i) flowing in a conductor is independent of the cross sectional area of the conductor.

Explanation

A closely wound cylindrical coil of insulated wire is called Solenoid.

Solenoid is a cylindrical coil of wire acting as a magnet when carrying electric current.

Explanation

The fabrication step where proper interconnection of circuit elements is made is called Metallization.

Metallization is often accomplished with a vacuum deposition technique

Explanation

Reliability is a measurement of consistency.

Reliability refers to the consistency of a measure

Validity refers to the accuracy of a measure

Explanation

Principle of superposition is applicable only for linear systems.

Superposition theorem states that in any linear, bilateral network where more than one source is present

Explanation

Some materials hold their electrons very tightly. Electrons do not move through them very well. These things are called Insulators.

In some materials such as glass, rubber, wood and most plastics, the electrons are held quite tightly.

These materials are called insulators.

Explanation

Ampere's Law states that any closed loop path, the sum of the length elements times of the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.

Ampère's circuital law relates the circulation of a magnetic field around a closed loop to the electric current passing through the loop.
