Hey I am really new to this and I am readying a Electronics Fundamentals book to learn how to work with electronics. I was wondering if I could damage a 2/3 watt speaker buy powering with a 7.4 volt Li-on battery or if I should use resistors to lower the amount of watts going to the speaker. I am talking about the 2/3 watt speaker you guys provide. I'm not wanting to damage it and every time I use ohms law it says that I should use a 27.38 ohms of resistance. Should I plug in a bunch of resistors or will the resistance of the wire itself be enough. I'm not sure how to figure out if I actually need a resistor at all when doing any of this. Any help would be nice. Thanks everyone.
