The power station has an efficiency of 0.34(34%) the energy supplied to the power station each second is 9X 10 8 j calculate the useful energy produced each second
Energy supplied to the station = 9 x 10^8 J/s
Efficiency of power station = 34%
That is, only 34% of the energy input is converted to the output and rest is lost in the process.
The amount of useful energy generated = 34% of energy input
= 34% of 9 x 10^8 J/s
= 34/100 x 9 x 10^8 J/s
= 3.06 x 10^8 J/s.
Thus, the power station produces 3.06 x 10^8 J of useful energy per second.
Hope this helps.
