P. 3902. By what factor would the dissipated power of an electric heating element change if it was connected to an ideal diode in series and this system was connected to an alternating voltage supply of 230 V, 50 Hz? What would be the root-mean-square value of the voltage across the electric heating element? What is the ratio of this value and the maximum of the voltage?
