derive relationship between commercial unit of energy and si unit of energy
See guys those who didn't get the answer properly
He had asked the derivation relationship b/w Commercial unit of energy
and
SI unit of energy
so 1st let us understand,
Commercial unit of energy = kWh
SI unit of energy = J
make sure u understand this much...
now read the question once more; they have asked the derivation b\w
commercial unit of energy and SI unit of energy
means,
" commercial unit .. " = "si unit...'
now,
commercial unit of energy = si unit of energy
i.e. J = kWh
now this can be written as,
J =1kW x 1h
J =1000W x 30x30 ( where 1kWh=1000W nd 1hr = 30 *30s)
J= 1000W x 3600
J = 3600*1000
J = 3.6*10 raised to -6 (made in standard form)
now 1 unit of energy means 3.6*10^-6
hence 1kWh = 1 unit
hope this hlped u ;)

So , firstly what is commercial unit of energy?
*A commercial unit of energy is defined as common unit of energy consumed in daily life i.e. in Housemeters....
So ,commercial unit of energy is
KWH (kilo watt hour)
1 KWH=1 unit
1KWH= 1?1000J/S?3600s(seconds)
1KWH=3600000J(joule)
1KWH=3.6?10^6 ans.
*The S.I. unit of energy is Joule...
*So difference between commercial and SI unit is commercial unit is used for higher consumed electricity and SI is for smaller...
Plzzzz cheerzz....

Commercial unit of energy.The SI unit joule is too small to express very large quantities of energy. Hence we use a bigger unit called kilo watt hour (kWH) to express energy .1 kWH is the amount of energy consumed by an electrical gadget in one hour at the rate of 1000 J/s or 1kW

Dear student,
Here is an answer to your query:
SI unit of energy is joule(J) and commercial unit of energy is kWh(kilowatt-hour).
In SI units,
Power = energy/time
P = E / t
or, E = P x t
1J = 1W x 1s
1J = 1Ws... (i)
Commercial unit of energy is kWh,
1 kWh = 1 kW x 1 h
= 1000W x (60 x 60)s
= 3600000Ws
= 3.6 x 10^6Ws... (ii)
From (i) and (ii) we get,
3.6 x 10^6Ws = 3.6 x 10^6 J
Since, 3.6 x 10^6Ws = 1 kWh
Therefore,
1 kWh = 3.6 x 10^6 J.
Hope this helps you :)

The commercial unit of energy is 1 kWh. One kilowatt-hour is defined as the amount of energy that is consumed by a device in one working hour at a constant rate of one kilowatt.
The SI unit of energy is Joule.
Therefore, the relationship between commercial and SI unit of energy is:
1 kWh = 1kW x 1h = 1000W x 1h = 1000(J/s) x 3600 s = 3.6 x10^6 J..
The SI unit of energy is Joule.
Therefore, the relationship between commercial and SI unit of energy is:
1 kWh = 1kW x 1h = 1000W x 1h = 1000(J/s) x 3600 s = 3.6 x10^6 J..
