Answer:

The energy produced equals 140.760 kJ

Step-by-step explanation:

The relation between power, current and voltage is

Power=Current* Voltage

Applying the given values in the relation above we get

Power=4.60* 3.40=15.64W

Now Since
$Power=(Energy)/(Time)\\\\Energy=Power* Time$

Again applying the calculated values we get

Energy=15.64* 2.50* 3600=140760Joules=140.76kJ
