16–28 In Figure P16–28, the load voltage is jVL j = 4160V

ðrmsÞ at 60Hz and the load ZL draws an average power of 12 kW at a lagging power factor of 0:75. Find the overall power factor of the combination if the parallel capacitance is 1 μF. Select the value of the capacitance required to raise the overall power factor of the parallel combination to 0:98.
