When comparing two sinusoidal voltage sources, one operating at 50Hz and the other at 60Hz, both will deliver the same power when connected to a 1-ohm resistor, assuming equal voltage levels. This conclusion is based on the principle that instantaneous electric power in an AC circuit is calculated using the formula P = VI, where V and I are continuously varying. The average power, which is typically of interest in AC circuits, remains constant across both frequencies under these conditions.
PREREQUISITESElectrical engineers, physics students, and anyone interested in understanding power delivery in AC circuits will benefit from this discussion.
