Energy calculations in C

[P.Copper]

Hi all,

I want to do energy calculations in c but i don't understand how to go about defining time in seconds. Can someone show or rather refer me to material where i can define time in seconds. thanks

hi set the timer to interrupt for every second and convert the power to 1 sec energy value and add it to already Energy value......

 

[jayanth.devarayanadurga]

1 sec = 0.000277778 hour

1 kWh = 3600s * 1 kW

1 kWh = 3600s * 1000 W

= 3600s(1kJ/s) = 3600 kJ


If W = 600W then

kWh = 3600 s * 0.6 kW

If W = 600W and time is 1 sec then

kWh = 0.000277778 hour * 0.6 kW

1J = 2.77778 × 10−7 kWh

Code C - [expand]

ISR()   // executes every 1 sec
{
   Energy += power / 3600;      // if power in kwatts then energy in kwh and also declare both of them in float
}
