Question

What is the cause of resistance offered by a metallic conductor for flow of electric current thorough it?

Answer 1

Cause of resistance offered by metallic conductor for flow of electric current through it:

• An electric current flow when electrons carry through a conductor, such as a metal wire. The exciting electrons can shutter with the ions in the metal.
• This makes it harder for the current to flow and sources resistance.
• Resistance in a metallic conductor if not supplied manually by a resistor or reostate is caused after the conductor is united to the circuit which causes the electrons to progress from the negative to the positive direction.
• Thus current flows the vice versa, and the flowing electrons dash with the fixed positive ions of the conductor, thus supplying resistance.

Answer 2

Cause of resistance for flow of electric

Explanation:

• In easy words, current may be a movement or flow of electrically charged particles and its unit of mensuration is amperes. once an electrical current flows during a conductor, it flows as a drift of free electrons within the metal. Electricity flows simply through a conductor as a result of the electrons ar liberated to move around within the object. Whenever there's a movement of electrons through a conductor, an electrical current is made. Current may also be divided into 2 types- DC and AC.
• Dc or Direct Current- because the name suggests, the present that forever flows in one direction and doesn't pull back and forth is named because the electricity. the foremost common example of DC is battery.
• AC or Alternating Current- the present that flows back and forth and not in one direction is termed because the AC.
• Before we have a tendency to really discuss the mechanism of current flow during a conductor we have a tendency to make a case for the thought of drift speed because it are needed in its description.
• Drift Velocity: the typical speed achieved by some particle just like the lepton thanks to the existence of electrical field is termed as drift speed. The particles are literally assumed to be moving on some plane and thence {the speed|the speed|the rate} may be termed as axial drift velocity.
