Hi Everyone
This is a very noob question about capacitors but last night I built a little circuit with a 555 timer and piezo buzzer and I decided to add a few capacitors to see what would happen and the sounds completly changed.
My question is what exacly happens to the sound and the square wave when you add a capacitor
1.) In series with the buzzer
2.) In parallel with the buzzer
3.) One in series and one in parallel at the same time.
The one in parallel seems do dissipate the energy when the signal is low so the sound is smooth and long. But what happens with the one in series?
For the 3rd question I was thinking something in the lines of this picture below. Excuse the bad paint work. But what would happen in that arrangement or if the parallel was in the base and the series was before the buzzer in the collector.
Thanks All
