A heater, represented as a purely resistive element, dissipates 1000 Watts of heat when connected across a 230-volt DC source. If the heater was to be connected instead to a sinusoidal AC source, what should be the amplitude (peak value) so that the average heat dissipated by the heater remains the same?
