derive relationship between commercial unit of energy and si unit of energy

unit=1KWH = 3.6*10^{6}

commersial unit of energy=KWH = unit = 3.6*10^{6}

so,

1 unit = 3.6*10^{6}

(3.6*10^{6}=1KWH written above)

1unit = 1 KWH

did u understand ...

plz thumbs up...

See guys those who didn't get the answer properly

He had asked the derivation relationship b/w

and

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...'

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,

**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)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 ;)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 :)
