Hi.
It's my 1st post so sorry if wrong place. I have tried to search for that topic but since I am not much familiar with electronics (yet) I might have missed it.
The problem/dilemma is that I want to turn a little fan using a remote wire (wire that puts out current when the radio is ON, it gives about 200-300 mA @12V). I don't want to use this to power the fan as I am not sure if it will somehow affect the head unit. So what I am trying to do is to use a Transistor or a SSR to power up the fan using the main power wire from the battery (if its not clear yet I am talking about a car setup here). SSR are hard to get for me (I live in Canada- circuits components are available online only- or at my work, but they will have to order it up). The Transistor is little easier to get, and my question is - If transistor is also used to amplify current- can that damage the fan? (I know the V is constant but I don't know exactly how the transistor works so I want to be safe).
Also If I wish to run more complex system then a fan (electric motors, lights, etc) could I use the same Idea (of course a higher Ic for the transistor)
