Ok, I am having trouble understanding how to calculate the resistance of resistors in parallel as you probably gathered from the name of the post.
I get resistors in series of course its really simple, and at first glance I thought resistors in parallel seemed simple as well but for some reason my answers are coming up wrong.
I'm not sure where I am making a mistake so I cant really explain it, instead I hope someone here can give me a very basic explanation of the formula and maybe go step by step through this for me;
3 resistors in parallel lets say 2000, 3000, and 4000
Also if its not too much to ask I was wondering exactly how a certain scenario would work say if you had 3 resistors as follows; =resistor


See? So that 2 are in series and 2 are parallel yet there are only 3 resistors. Would I calculate the 2 parallel resistors first then simply add the left over resistors value?
Thanks in advance for the answers!
