Abstract
Our experiment to measure the speed of alternating electricity is briefly reported here. It is found that the speed of alternating electricity within the metal wire is not constant, which is depended on the circuit parameters. In most cases, the speed of alternating electricity is less than the speed of light. However, our recent experimental results show that at less than 3 MHz frequency region and under our circuit parameters, the speed of alternating electric field can be 20 times more than the speed of light.
