3) A $40\mathrm{Hz}$ transformer is to be used on a $50\mathrm{Hz}$ system. Assuming Steinmetz's coeff. as 2.6 and the losses at $40\mathrm{Hz},2.2\%,0.7\%$ and $0.5\%$ for copper, hysteresis, and eddy currents respectively, find a. The losses on a $50\mathrm{Hz}$ for the same supply voltage and current b. The output at $50\mathrm{Hz}$ for the same total losses as on $40\mathrm{Hz}$
