Electronics

1. components

   • Cell
     • An electric power source that have positive an negative poles on both sides. They come from different amounts and sizes. They range about 1.5 to 9 V
   • resistor
     • A component that resists on the flow on the electric current
       • Tolerance
         • In the picture with the resistor shows that it comes in a different colour. It shows the value it contains
           • The first band tells us the digit. The second tells us the other digit.The lst band which is below tells us how many zeros are in the digit. The unit is ohms
   • Led light
     • Which stands for light emitting diode which gives out light when an electric current goes through it
   • Transistor
     • Electronic switches that are the main components on most devices.The transistor contains 3 legs which are the bace ,emitter and collector
   • Wire
     • Used to connect with the other components so that the electricity goes through the circuit. They should be soldered when you connect the components together
     • Conductors
       • electric current to pass throgh easily
     • Insulators
       • wont allow current to pass easily
     • semi conductors
       • Ability to conduct electricity somewhere between conductor and insuator

2. circuits

   • Parallel
     • Has more than one paths for electric to flow through
   • series
     • A circuit in which the resistors,component and the wires are arranged in achain style form

3. Gates

   • Or gate
     • Just like the AND gate 2 inputs and one output but instead of both 1s as outputs and come out 1 as an output, it would take both 0 inputs to make the output 0
   • And gate
     • Has 2 inputs and it comes out with one output> I would be 1 if both inputs are 1
   • Nand gates
     • The gate is exactly the same as the ANd gate but instead the output is opposite
   • Inverter
     • Reverses the input as the output
   • poles and throw
     • single pole single throw
     • single pole double throw
     • double pole single throw
     • double pole double throw
