Standing-Wave Current vs Traveling-Wave Current
Keith Dysart wrote:
Are you really saying that if I measure the instantaneous voltage and the instantaneous current then I can NOT multiply them together to obtain the instantaneous power? It certainly works some of the time. If I can not do it all the time, when can I do it? Actually, "multiply" is ambiguous. You need to take the *dot product* of the voltage and current to obtain power. -- 73, Cecil http://www.w5dxp.com |
