Answer Posted / deepakindi1
current through capacitor=
ic= c dvc/dt
ie current through capacitor is a function of rate of
change of voltage applied across it, as applied voltage is
sinusoidal sine wave ,if u take a slope at zero croosing of
wave form rate of change of the voltage is maximum so is
the current at zero croosing of wave form is maximum. that
ic reaches its maximum before applied voltage that y
current through capacitor leads voltage

why capacitive load is not used in routine life????any reason is there ??????
We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
