- - - - Motor
      - Resistor
      - Bell
      - Light bulb
    - - Breaker switches are automatic fuses
      - Earth-leakage circuit breakers protect against current leakage
      - Fuses melt in order to interrupt the current when it is too high
- - - - NTC
      - PTC
  - - - Base
      - Collector
      - Emitter
- - - - consist of a magnet,inside which there is a coil ending in two separate semicircular conductors:commutator.The brushes are in contact with the commutator
    - - Are practically identical to dynamos,the difference is that the collector consists of two rings,each ring have contact with a brush
- - - - The heat energy generated by an electric current is called the Joule effect.
  - - - An electric current heats a metallic filament that produces light
    - - Inside the tubes there is a metallic filament an inert gas and small quantity of mercury.
      - Low energy light bulbs
        
        Are fluorescent lamps that consume much less electric energy than conventional bulbs.
  - - - This effect is used in electric motors and relays,it is the basis of electromagnet
- - - - The rms value of an alternating electric current is the value that a direct should have to produce the same energy effect
    - - We can use transformers to increase and reduce the alternating voltage
