I have the project of making a touch switch using the IRFZ44N MOSFET for making a small led glow and stop glowing when I touch the probes. I thought of using a relay if I have to make a bulb glow, by connecting to the plug directly. I searched on the internet and found that most projects used 5V relays. But is it a problem if I use a 12V relay, instead of a 5V relay?
(Please don't mind if the question sounds silly, I am new to electronics and electrical)
