Consider following: The RMS value of any sine wave is Ampiltude/sqrt 2. It is independent of frequency. So consider two sine wave generators, one generates at 50 Hz and the other one generates at 500Hz. Both have same amplitude A for volt wave and B for current wave. Consider same pure resistive load connected to both. The power equation for both would be Vrms.Irms = AB/2. Que1. Is this per wave cycle or per second ? Que2. Is it correct that the 500Hz wave will deliver same energy as 50 Hz in 10 times LESSER time per cycle?? Thanks in advance.
