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:
- 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.
