Hello SweetBee3768,
Thank you very much for your question! "Req" stands for equivalent resistance. Equivalent resistance is calculated differently depending on the type of circuit. If the circuit is in series, then you simply need to add all the resistors in your circuit.
However, if your circuit is in parallel, then the calculation you need to do will look like this:
1/Req = 1/R1 + 1/R2 + 1/R3 …..
You must therefore calculate the sum of the inverse of all your resistors. Here is a something that could greatly help you:
I hope I've answered your question. Don't hesitate to write back if you have any questions!
