Question

conclusion of effect of electric current​

Answer 1

Answer:

This is because when a current passes through the wire, it behaves like a magnet and therefore deflects the magnetic needle of the compass. ... When an electric current is passed through the wire, the iron piece behaves like a magnet.

Answer 2

Answer:

Effects of electric current:

• The direction of electric current is taken as opposite to the direction of the flow of electrons (negative charges).
• inside a solid, the atoms are packed together very closely to each other but electrons are able to travel through the solid crystal as if they were in vacuum.
• When a steady electric current flows in a conductor, then the electrons in it move with the certain average drift speed (the constant speed of the electrons inside the conductor with which they move under the effect of external electric supply) of the the order of 10^ -4 m/s. Thus, flow of charges produces current in wire
