What is a circuit?

its a closed pathway in which electronsflow. It contains a power supply, current nd other components.

voltage

it's the electrical charge of the power supply 
se representa en voltagw (v)
 

Current

it's the flow of elctrons in a circuit

siempre va de negativo a positivo

se representa en amperes (I)

resistance 

it's the component tat opposes to the flow of current

ohm/ omios  

  types of circuits

Series: 

It's a closed pathway in which the current flows throgh some components without branching (-) solo hay una entrada, si algo se daña el resto tambien.

formula: resistncia equivalente es igual a la suma de las series 
Req= R1+r2+R3+R4...+Rn

Parallel:

 It's a closed pathway in which the current flows throgh some components doing branching.

Formula:
  1. F1 for 2 resistors 
         Req= R1xR2/R1+R2
      2. for 3 or more
        Req= 1/ 1/R1+1/R2+1/R3+1/R4...+1/Rn

Mixed:

It`s a combination of series and parallel 
 

VIR

 es una formula que se usa para hallar el voltaje, la corriente y la resistencia

Reduction of circuits

It's to take the circuit to it's minimum expression with only one resistor.
