- - - - when the electric current flows through the conductor, a part of this is converted into heat energy, which is a waste of energy
      - heat produced can damage the insulation and other electrical components, or even case a fire
      - reduces the life of several components in the circuit
      - additional cooling system needs to be added to the circuit to counter the heating effect, which adds to the cost
  - - - R = resistance, unit Ohms
      - V = voltage, unit volts
      - I = current, unit Amperes
- - - - Formula: V = I * R
  - - - Formula:
- - - - r = internal resistance of circuit
      - R = Load Resistance of Circuit
      - equation can be modified into e=V+Ir
