The detailed discussion about the flow of current through metallic conductor and electrolyte.

Explanation:

(I) Metallic conductor

  • Free electrons are responsible for the flow of current in a metallic conductor.
  • The particles that carry charge through wires in a circuit are moving electrons.
  • The direction of the electric field within a circuit is by definition the direction of pushing the positive test charges.
  • Thus, these negatively charged electrons move in the opposite direction to the electric field.

(ii) Electrolyte

  • In an electrolyte, ions move towards the cathode or anode depending on their charge.
  • When a wire is connected between the cathode and the anode, electrons leave the cathode and enter the anode.
  • Thus in an electrolyte, the movement of ions is responsible for the electric current.
