Electric and Electronic Circuits

1. Components

   • Power Sources
     • Cell
     • Battery
     • Power Supply
   • Load Devices
     • Lamp
       • Convert electrical energy into light energy
     • Motor
       • Converts electrical energy into kinetic energy
     • Buzzer
       • Convert electrical energy into sound energy
     • Diode
       • Only allow current to pass through them when thet are forward biased.
     • LEDs
       • Is a diode with the same characteristics of them and that lights up when current pass through it and its maximum voltage is 2v.
     • Resistor
     • Variable Resistors
       • LDRs
         • Resistant value that varies according to the amount of light that hits them
       • NTCs
         • Resistant value that varies inversely with the temperature
       • PTCs
         • Resistant value that varies directly with temperature.
     • Potentiometer
       • Resistor with a value set by the user from a range of operating values
     • Capacitor
       • Store electrical energy. The amount of energy that can store depends on the capacitor.
     • Transistor
       • It has three parts to connect: The base, the emitter and the collector. Depending on the amount of electrical current that reaches the transistor through its base,it can function like a switch or a current amplifier.
   • Control and Protection Devices
     • One-way switch
       • Open and close the circuit when they are actuated
     • Push Switch
       • Open and close the circuit,but only while we keep them pressed
     • Two-way switch
       • Open and close the circuit. They can also open some circuits and close others simultaneously
     • Relay
       • Electromagnetic components.They are activated when an electrical current flow throgh them. They are used to control the opening and the closing of circuits when they are activated by a secondary circuit.
     • Fuse
       • Protect the components of electric circuits from power surges
