I try but still difficult, I can’t find any information on Internet???Best have a stab yourself and post what you think, members will comment on your answer and provide guidance....but wont answer the question for you.
Your calculation is correct but the answer is very badly wrong because you have put in some incorrect data through misreading the question. You have shown the efficiency as 0.75 % instead of 75% (=0.75) Therefore your answer is 100 times too large. Less importantly, 1 hp = 746W.
Think about what a motor of 0.75% efficiency would be like: It would waste almost the entire energy input. Also think about your answer of 1360A. The line and neutral cables to carry that would be as thick as your arms, yet the motor is no larger than the one in a good domestic pressure washer that runs on a 13A plug.
This is what we call a sanity check and it's worth doing every time. If the results of your calculation suggest that a cable must be 10000 km long or an electric shower will run on 0.01W, you can tell from real life experience that the answer is not sensible and probably indicates an error in the working or incorrect input data.

What is the answer???
Did you accept this answer????Lucien has explained where your mistake is. This should allow you to rethink how you calculated it. It's no good just giving you the answer.
Did you accept this answer????
Absolutely joke , I find professional company for assignment and doing all answers wrong now waiting for refund.
They put Volt-240 usually in Uk is -230.
In formula the same .
I’m very disappointed now .
I talking about answer 7.77A why /240V , they need to used correct formula answer not 7.77A.????2.5 x 746 = 1865 Watts.
Which answer are you talking about accepting?
Edit: I may have misunderstood your post.
The quoted voltage isn't over relevant. The declared UK voltage is 230 -6%/+10%. This gives a range of 216.2 to 253.0v.Did you accept this answer????

They need to by used this formula???I wouldn't get hung up about the 230v issue - your calculation was wrong by a significant amount because of the percentage error.
Edit: is Lucien correct.? Did you buy these answers? You really need to try the question again yourself.
I try my self but I’m too busy all first 8 question is w
I try my self but still confused, that asking people for help ???Looks like part of your message is missing, but I can see the part which says you are too busy to try it yourself. If this is the case then there really is no point in doing the course. Would you really be happy if you passed a course like this without understanding it?
