Hi everyone, I've tried searching over and over again in my textbook and online, but I can't seem to find anything about the specific nature of parallel batteries. So I have the following problem that I can't get anywhere with: There is a 6 ohms light bulb connected to two 1.5 V batteries that are in parrallel. Each battery has an internal resistance of 0.5 ohms. 1. What is the current through the bulb? (No idea on the formula. ) 2. What is the terminal voltage across each battery? (No idea. ) 3. What is the power consumption of the bulb? (I'm guessing after finding the current, the power consumption will just be I^2*R?) 4. By what factor have you shortened or lengthened the life of the batteries? (All I know is that the life is lengthened, but I have no idea what the formula is.) Thanks sooo much everyone for helping out!
