Final answer:
The student question relates to determining electrical parameters for a heater using a three-phase half-wave rectifier, focusing on output power and voltage and current values.
Step-by-step explanation:
The student's question revolves around a three-phase half-wave rectifier supplying power to a heater with a temperature heating coefficient of 10W/°C effective power. To solve this problem, we need to determine several electrical parameters, such as output DC power, average and RMS load voltage, and current using electrical theories and formulas applicable for rectifiers and heating systems.
