Question:

An industrial process heater delivers power from a 480-V dc generator to a 30-Ω load resistance that produces 7680-W heat when fully on. A reduced operation requires only 4224 W of average heat generation rate. Determine

(1) The required series rheostat resistance and the process energy efficiency and

(2) The switching duty ratio D and the energy efficiency if an ideal power electronics control is employed.
