SSC JE Electrical 2018 with solution SET-1
Calculate the value of the resonant frequency (in kHz) of a tank circuit having the capacitance of 0.01 mF and inductance of 0.01 mH?
It means that the efficiency is maximum at a load when the copper-loss (variable loss) equals the core-loss (constant loss). Thus for maximum efficiency Copper loss(Variable loss) = Core loss(constant loss) Core loss = 450 Watt = Copper loss Cooper loss = 450 Watt
