Answer:
Motors 175 kVA
Lighting 315 kVA
Other loads 35 kVA
Step-by-step explanation:
The total load on a certain service is 525 kVA.
One-third of this load is from motors, then
[tex]\dfrac{1}{3}\cdot 525=175\ kVA[/tex]
is from motors.
[tex]\frac{3}{5}[/tex] is lighting, then
[tex]\dfrac{3}{5}\cdot 525=3\cdot 105=315\ kVA[/tex]
is lighting.
[tex]\frac{1}{15}[/tex] is from other loads, then
[tex]\dfrac{1}{15}\cdot 525=35\ kVA[/tex]
is from other loads.
