    Okay so I feel dumb. I'm just trying to make a circuit with a 9v supply, that activates a relay with a 9v nominal voltage a with 579 ohm coil resistance and a nominal power rating of 140 mW with a 1n4002 diode. I'm really confused on how to use ohms law and stuff to figure out how to make these things work. Please can someone help me out, I thought I knew what I was doing but now I feel like I have no clue anymore. Obviously I'm still very new to this whole thing so any and all help is greatly appreciated. :)
