Question

Explain how electric current with Lorentz-Drude theory of electrons.

Answer 1

• Lorentz-Drude proposed that conductors like metals contain a large number of free electrons.
  
• The positive ions are fixed in their locations. (The arrangement of the positive ions is called lattice).
  
• The negative ions (electrons) move randomly in lattice in an open circuit.
  
• When the lattice is closed the electrons are arranged in ordered motion. This
  

causes electric current to flow.
