What is the
physical significance of
resistance?
Answers
Answer:
what is the physical significance of resistance? Electric resistance is causes due to thermal motion of electrons and due to collision of electrons with atoms. Electric resistance is smiler as the mechanical friction because electric resistance oppose the flow of current.
Explanation:
Answer:
Electric resistance is causes due to thermal motion of electrons and due to collision of electrons with atoms. Electric resistance is smiler as the mechanical friction because electric resistance oppose the flow of current.
The collisions of electrons with other atoms and electrons is the reason for the resistance in the path of current inside a conductor. With the increase in temperature the time between successive collisions decreases hence the drift speed decreases and we say that Resistance increases.
