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

                 $=\frac{1}{3} \times 525 \\\\=175 \text{kva}$

Amount of load which is from Lighting

               $=\frac{3}{5} \times 525\\\\=3 \times 105 \\\\=315 \text{kva}$  

Amount of load which is from other loads

                 $=\frac{1}{15} \times 525 \\\\=35\text{kva}$  

Answer 2

Total load given is = 525 kva

The breakdowns of the loads are as follows-

Load from motors =$\frac{1}{3}\times525=175$ kva

Load from lighting = $\frac{3}{5}\times525=315$ kva

Load from other miscellaneous things = $\frac{1}{15}\times525=35$ kva
