Define resistance


Current is the aggregate flow of electrons through a wire and can be defined as the rate of electron flow. Resistance is defined as an opposition to current flow. An electrical circuit must have resistance in it in order to change electrical energy to light, heat or movement.

  • Resistance is known that the directed movement of electrons constitutes a current flow.
  • It is also known that the electrons do not move freely through a conductor’s crystalline structure.
  • Resistance is an inherent opposition to the flow of electrons present in conductors.
  • Inductance is the property of any circuit to oppose any change in current, whereas capacitance is the property of a circuit to oppose any change in voltage.
