[QUOTE="NascentOxygen, post: 4531723, member: 336970"] Hi bibo_dvd. [PLAIN]http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif[/PLAIN] [Broken] If R6 were equal to 0Ω then you could indeed say V7=E/R7 Ohms Law requires E to be the voltage across R. You can't consider a voltage from just anywhere and divide it by any resistance you choose. E must be the exact voltage across exactly that R. In your circuit, R6 is in the way, meaning that E = (the voltage across R7) + (the voltage across R6). [/QUOTE]
