Hi guys, I kinda need help on my IA because I just found out from my school's other physics teacher that I shouldn't do RC circuits on my IA. I was planning to investigate the affect of current on the time constant of an RC circuit. I don't know whether I should continue doing it or should I change my topic. I also need help on which topic should I moved to if that's the case. I wanted it to be related to electricity and electronics. Any ideas?
