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.
