ANALOGUE ELECTRONICS

ANALOGUE ELECTRONICS

1. RESISTANCE

   • For measuring
     • Ohmmeter
   • Is a measure of the difficulty to pass an electric current through that conductor
   • Ley de Ohm
     • R = V + I
     • The radio of voltage across it (V) to current through it (I)
   • Determinate by 2 properties
     • Material
     • Geometry (shape)

2. RELE

   • Control a circuit by a separate low-power signal
   • Estructure in 3 parts
     • Coil of wire wrapped
     • Iron yoke
     • A movable iron armature
   • TYPES
