when do we convert time to second and when do we convert it in hrs...

when do we write in jouls, watt and kilowatts?

if i guessed ur q's correctly then..
to calculate Kwh you need to convert in hrs..
to calculate I=Q/T you need in seconds..
to calculate E=Pt we need Kwh

i thought tht for P it is in watts... bcz... joules and watts are related
