am i being TROLLED?
these delta9 persei's are still up for purchase.
where or whom should i ask question for this old stuff?
I'm not here to troll, I'm here to help.
A series circuit is one in which resistors are arranged in a 'chain', their ends are linked together one after another and the current has only one path to take. The current has to go through all these resistors to complete a circuit so you just add resistors to get a total circuit resistance.
In parallel circuits the resistors wired so that their input ends are connected together and the output ends are connected together. In parallel circuits the electrons can flow through any path. They will generally take the path of least resistance but with a lot of electrons and many paths some will go down each one. To calculate the resistance of a parallel circuit, the resistors must be divided. Where Rt is Resistance total and each Resistor is R the formula is
1/Rt = 1/R
1+1/R
2+1/R
3 .... etc to infinity.
For your specific question 2 4Ω carts on a Double top which is wired in parallel
1/4Ω + 1/4Ω
.25 + .25 = .5
1/0.5=2Ω total circuit resistance.
However with parallel circuits where all resistors are identical there is a shortcut. Where N is the Number of resistors the formula is Rt=R/N. Two 4Ω carts on a double top, you divide the 4 ohm resistance per cart by 2 resistors to get 2Ω resistance for the circuit.
You should ask me those questions about old stuff. I bought 3 V1 Persei kits long after they were out of production just to get my hands on old stuff and still have two working double tops. I really like 2.4Ω carts on the double top with an SS kit+ AW 18650. I might try a box of 3.0Ω carts next.
