They seem to be asking a lot of technical questions which licensed hams should know.
Your browsers AI search engine should be able to find the answer in case you don't know.
They are reusing some questions from the last time the prize was an ICOM IC-7300 in 2024.

I encourage you to post both the question and the answer and not just the answer..
Historically, GigaParts has repeated the same questions from one sweepstakes in later ones.
If you post the question, then in a later sweepstakes when they repeat the question you can do a
keyword search of the previous thread and quickly find the answer.

How many watts are consumed in a circuit having a power factor of 0.2 if the input is 100 VAC at 4 amperes?
Answer: 80 watts
Entry page https://www.gigaparts.n
This question used to be in the pool of exam questions for the Amateur Extra licence but isn't in the current exam pool.
E=100 V
I=4 A
Power Factor (PF) =0.2
The consumption with a power factor of 1.0 would be defined by Ohm's law:
P=E⋅I=100 V⋅4 A=400 W
We call this result the Apparent Power, and often refer to it with the symbol S:
S=Papparent=400 W
To determine the real power, the apparent power needs to be multiplied by the power factor:
PReal=S⋅PF=400 W⋅0.2=80 W
