(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The circuit has a battery Voltage of 30V, a resistor of R1(8ohms), R2 (2Ohms) and R3 (4ohms) in series. Calculate the voltage drop over R1

2. Relevant equations

Please give me the proper equation of this? The one i've got says you take 30-8I-2I-4I=0

Wich gives you current of 2.142 and not the voltage.

3. The attempt at a solution

Now what i tried doing is this.

30V-8-2-4=0

30V=14

V=14/30

V=0.466

but i'm sure its wrong.
