Sonoluminescence Help!
Hello everyone!
Working on my sonoluminescence project in the University of Washington, I encountered some (frustrating) issues. I have little/no electronic experience so please bear with me. Any help is appreciated.
First, looking at the images below, can anyone tell me what is the wattage specification for the resistor? suppose 30 watts are coming from the audio amplifier.
Second, I need a coil wrapped around a plastic spool with a ferrite core to adjust the inductance. How many turns of wire do I need? Whats the equation for this calculation? I'm using a spool with a 2 cm diameter and 2 cm length. My ferrite rod has a permeability of 600 and has an AL value of 74 (the website mentions that is the nH/Square Turn or nH/N2)
Lastly, where can I order an appropriate amplifier? The lab I'm working in does not seem to have an audio amplifier. I need something that is not crazy expensive but will still achieve my needs in this experiment.
Thanks!
