Howdy all,
First of all, thanks for having this site here... I've been itching to learn electronics for quite some time now, and I've finally decided to get going on it!
I've read the very basics, resistors, current, power, etc. A few things are still a little unclear to me:
1. With regards to volts... let's say I have a piece that uses 6V, and a piece that uses 2V. If I run them in series, a 9V battery would be sufficient, as long as I added a resistor. Is that correct? (And the resistor would be found based on ohms law, rounding up... correct?)
2. What if I ran the two in parallel? Would I have to add a resistor to one of them for them to both function?
3. The above comes from a basic circuit I'm pondering on, which would have a buzzer and led both on, once current was provided to the circuit. Then, at a button push, the current would switch to a pair of wires to fire a firework. The idea came from several I saw online, but I'm trying to work up my own method so I can learn from it.
The buzzer I'm looking at as an example is here:

It's data sheet indicates it's 'Rated voltage' is 12v... but it's 'Operating Voltage' is between 6 and 16. Does this mean that if I had a LED at 3v, I could run the two in series with a 9v battery and still have sound?
4. This gets a little more difficult to explain, but I'll try. Am I correct in my following guess:
If I'd like to instead have the option to fire up to four fireworks at once (on one button press)... do they still receive the same current/voltage, but the battery's life is consumed faster... or did I just skip a step?
Thank you very much! Your answers will help me learn much quicker!
