What will be the energy loss per hour in...

What will be the energy loss per hour in the iron core of a transformet if the area of its hysteresis loop isequivalent to `2500erg//cm^(3)`.
The frequence of alternating current is `50 Hz`, The mass of core is `10 kg` and the density of iron is `7.5gm//cm^(3)`.

A

`2xx10^(2)Joul e`

B

`4xx10^(3)`Joule

C

`6xx10^(4)`Joule

D

`8xx10^(5)`Joule

Text Solution

Verified by Experts

The correct Answer is:
C
Total energy loss `E=nAVt=nA(m)/(d)t`
`=50xx2500xx10^(-1)xx(10)/(7.5xx10^(3))xx3600`
`=6xx10^(4)`Joule
