Ok. im adding this up time and time again and its just not making no sense. Im sitting here trying to brush up on technical math skills this week before i get my soldering iron so i dont mess nothing up. and here i am i cant understand the basics.(adsbygoogle = window.adsbygoogle || []).push({});

I have a 20volt power supply and 4 resistors: R1, R2, R3 and R4. R1 = 200Ω R2 = 700

R3 = 300Ω R4 = 400 Ok what i did was use ohms law and all the other crap. so anyways in order to determine how much voltage is going through each individual resistor i need to multiply current by resistance. I did that to each one and when i get done i keep coming up with 19.68 rather than 20. Can someone please help me figure this out before i go and blow a circuit board or something one day not knowing basic stuff? OH yeah and the current running through the circuit is 0.0123 milliamps
