If i connect a power source to an audio source using a resistor and then a capacitor will it amplifier the audio signal Answered

this may be what you are looking for. if you don't feel like thinking much

No. This requires an audio amplifier. There are many amplifier ICs such as the LM386 (and many, many others) that can amplify an audio source. I'd look into one of these.

And don't plug anything into the mains until you know what you're doing.
