Question

The total load on a certain service is 525 kva. one-third of this load is from motors; 3/5 is lighting; and 1/15 is from other loads. what is the kva of each of these breakdowns of loads? match with the correct answer shown below

Answer 1

Answer with explanation:

Total Load on a Certain Service =525 kva

Amount of load which is from motors

`=(1)/(3) * 525 \\\\=175 \text{kva}`

Amount of load which is from Lighting

`=(3)/(5) * 525\\\\=3 * 105 \\\\=315 \text{kva}`

Amount of load which is from other loads

`=(1)/(15) * 525 \\\\=35\text{kva}`

Answer 2

Total load given is = 525 kva

The breakdowns of the loads are as follows-

Load from motors =
`(1)/(3)*525=175` kva

Load from lighting =
`(3)/(5)*525=315` kva

Load from other miscellaneous things =
`(1)/(15)*525=35` kva
