Description : reasons the transposition of conductor

Last Answer : Following reasons the transposition of conductor:  1. Due transposition of conductor inductance of each line is same LA = LB = LC, So drop due to inductive reactance in each line is same so ... interferences are less due to transposition.  Figure of transposition of conductor: 

Description : What is difference between Conductor and insulator ?

Last Answer : Conductor is a material that offers no resistance to the flow of current, while an insulator is a material that offers total resistance to the flows of current, It doesn't allowed any flows of current.

Description : Which is the best conductor: silver, carbon, or iron?

Last Answer : Silver is the best conductor. Carbon is the semiconductor. Iron have less conductance as compared to silver.

Description : How does the resistance of a conductor compare to that of an insulator?

Last Answer : The resistance of a conductor can be significantly lower than the resistance of an insulator, depending on each material's atomic properties.

Description : In a metal conductor, what is a free electron?

Last Answer :  When many atoms are close together in a copper wire, the outermost orbital electron of each copper atom can easily break free from its home or parent atom. These electrons then can migrate easily ... random. Such electrons that can move freely from one atom to the next are called free electrons.

Description : A 3 layer, total diameter of an ACSR conductor is 5 cm. Find the diameter of each strand?

Last Answer : A 3 layer, total diameter of an ACSR conductor is 5 cm. Find the diameter of each strand? 1 cm

Description : lf the wire which is vertical to this page has electron flow downwards the conductor will have

Last Answer : lf the wire which is vertical to this page has electron flow downwards the conductor will have a counter-clockwise field in the plane of the paper

Description : When electric current passes through a metallic conductor, its temperature rises. This is due to?

Last Answer : When electric current passes through a metallic conductor, its temperature rises. This is due to collisions between conduction electrons and atoms.

Description : The thickness of insulation provided on the conductor depends on?

Last Answer : The thickness of insulation provided on the conductor depends on the magnitude of voltage on the conductor.

Description : The insulation on a current carrying conductor is provided?

Last Answer : The insulation on a current carrying conductor is provided to prevent leakage of current, to prevent shock.

Description : Heat in a conductor is produced on the passage of electric current due to?

Last Answer : Heat  in  a   conductor  is  produced   due  to  frictional  collision  of  electrons   flow  as  they  conduct  current.

Description : If a wire conductor of 0.2 ohm resistance is doubled in length, its resistance becomes?

Last Answer : If a wire conductor of 0.2 ohm resistance is doubled in length, its resistance becomes 0.4 ohm.

Description : The resistance of a few meters of wire conductor in closed electrical circuit is?

Last Answer : The resistance of a few meters of wire conductor in closed electrical circuit is practically zero.

Description : The resistance of a conductor varies inversely as?

Last Answer : The resistance of a conductor varies inversely as area of cross-section.

Last Answer : If B is the flux density, I the length of conductor and v the velocity of conductor, then induced e.m.f. is given by Blv.

Last Answer : When a conductor carries more current on the surface as compared to core, it is due to skin effect.
