So far I've only worked circuits with resistors in series, but there is another way to place the resistance, named resistors in parallel, there you have an example in the following image:

This particular class of circuits are solved in a different way because the resistors are in parallel with each other. We need to obtain the total circuit resistance, in case one or more resistor are parallel we must do the sum of the inverse of the sum of the inverses of each of the resistors:

But this current value corresponds to the total value of the circuit, to get the individual current from the two resistances(12Ohm and 24Ohm), we first multiply the total current value by the total resistance:

*V=I*Rt=(1,5A)(8Ohm)=12V*Now we will divide the 12V between the two resistors individually to obtain the current value:

*I=12V/12Ohm=1A*

*I=12V/12Ohm=0,5A*

Conclusions: The voltage will be the same between the elements situated in parallel, and the current will be divided in equal parts between the circuit elements.
