Hi :), i have a speaker with 0,5W and 8 Ohm. Did i need a resistor when i put this mini speaker on a 9V batterie? |
| james_s:
Why would you put a speaker on a 9V battery? Do you also have some electronics to make it do something? |
| Irukandji:
I will try to make a noise with 2 transistors and 2 capacitor. But i don't know, if i need a resistor for the speaker, when i try this with a 9V battery. |

If you want better responses you will need to provide better information about what you are trying to do and some schematic of your work. |
| james_s:
Probably not specifically for the speaker, but post the schematic you are trying to use and that will help. |
