Darren, I have difficulties to follow your argumentation. Is this

hence electrical power is not a function or proportional to its frequency. what you want to say? And is the "the well known r.m.s. equation" you mention all the time the supposed proof of your thesis? Ok, please elaborate what formula you exactly mean. Please be as concrete as possible, so that we can discuss this issue by the help of physics. I still don't know what you try to tell. Kai Hi Kai, If I have 10Hz, 10V r.m.s. signal feeding a 10R resistor, the power or heating effect being dissipated in that resistor is 10 Watts??, assuming my voltage generator has zero source resistance, i.e., 10Vr.m.s. is dropped across the load resistor. Now, I increase my frequency to 1MHz, the amplitude is still 10 Vr.m.s., what is the power being dissipated in load resistor now. According to MR OHM, the power being dissipated is still 10 Watts, in fact it remains 10 Watts, irrispective of the frequency. Electrical power is proportional to current^2 or voltage ^2, it is not proportional to its frequency, for that we simply convert time varying signals to their equivalent d.c. value and hence r.m.s. equation. Keep well Darren |
