you can excite dc too with a bell....
Actually, the reason AC current is so widely used is because it can be transformed. That is to say; From the power station, electricity comes to the consumer over transmission lines. The higher the voltage, the less energy is lost through transmission. This fact makes AC current much more compatable for commercial use and less expensive to provide. It is also good to note, DC current at the voltage of 120v is much more dangerous than AC. While they are both capable of killing the common adult at this voltage, DC current is much more lethal because it tends to hold it's victim with more vigor.....................Ethos
