apparent power question

[SiddMartin]

what is the method to find this answer?

What is the apparent power of a 20A load operating at 120V, with a power factor of 85%?

2,400W
1,920W
1,632W
2,400 VA

I thought of 20*120=2400*85% = 2040va somethin isn't right

 

[infinity]

What about 2400VA?

 

[infinity]

I had to think about the formula's:

Real Power = V*A * PF
Apparent Power = V * A

thank you, that solves 2 questions:smile:
