Hi

Hope someone can help with my question;

I've got a wireless webcam that runs on a 9volt battery. As the camera is going to be left for long periods, I'd like to power it with a car battery, which means it can run unattended for a lot longer.

However, I'm not sure how I should reduce the output of the 12v car battery to the webcam's 9v.

Is it as simple as working out what resistor should go inline between the battery and cam and put that in, or is it going to be more complicated than that?

Any help much appreciated!
