The concept of dipole

Lecture's plan

Introduction

  1. The concept of dipole
  2. The current that flows in a dipole
  3. The difference of the terminals' potential
  4. The power in a dipole
  5. Signs convention as load
  6. Signs convention as source

This course introduces the concept of dipole and defines the current that flows and the voltage across its terminals. It will be obtained the expression of the power absorbed or supplied by the dipole. The absorbed power is given by the product , if the reference signs of the current and voltage were chosen according with the signs convention as load. It is given by the inverse of this product (as supplied power), if the reference signs were chosen according with the signs convention as source.
