Where do you put the jumper cable on a dead car?
Clamp the black jumper cable (the negative one) to the negative battery terminal of the donor car, which will be marked with a “_”. Secure the clamp tightly with the battery. Take the other end of the black jumper cable and clamp it to the dead car’s flat, the metal surface on the engine.
How do you jump start a dead car battery?
In order to properly jump-start a car you will need to create a circuit that carries the current from the live battery over to the dead one.

You only make a spark when you complete, or break, an electrical circuit. So the cable clipped on the battery should be attached first, and removed last, because you don’t want the spark to be right there at the battery. But in the many times I have charged batteries and made jump starts, I never had a problem.
