What happens when the car battery connectors connect together?
When a car battery in connected to itself (i.e. You connect jumper cables onto a battery and then connect the other two connectors to each other), you create a continual circuit with the battery and nothing else. A similar effect is when you hold a 9 Volt battery to your tongue and you feel a small but continual "zap". Imagine this effect, but much greater. Sparks will appear when the connectors are first connected. Warning: Do not do this. This will damage your car battery. The only reason you should connect a car battery through jumper cables is to connect it to another car's battery in order to "jump" a car.
