If a transformer has 50 turns in the primary winding and 10 turns in the secondary winding, what is the reflective resistance if the secondary load resistance is 250 ?

 

[i=p/u]

cant remember this stuff, but isit?

ns/us/vp =

b

 

[Top Cat]

I thought it was

i=p/u

Let me reflect on this for a while...

I predict several more of these types of questions!
If a transformer has 50 turns in the primary winding and 10 turns in the secondary winding, what is the reflective resistance if the secondary load resistance is 250 ? A. 250 B. 25 C. 6,250 D. 62,500

Think you may need our mathematicians section for this one, but they're still tied up calculating the neutral current for a 3-phase supply.

I think everyone is still recovering from all the plumbers who came on here.

thanks for reply. Can you explain it?

What exam is this for?

You should do your own homework.

Yes, I can. I haven't seen your attempt yet. This forum is not set-up to do you homework for you, however, if you make a genuine attempt and make a mistake we will tell you where you've gone wrong.

A little word of advice if I may, be a little less bolshie with your thread titles when wanting help with your homework mate. As an example, http://www.electriciansforums.net/e...l-electrical-forum/59605-answer-question.html Sounds very aggressive, you wouldn't walk into a site cabin and demand answers would you?
Also, as it's a homework question, have a go at the answer and explain why you think that. You'll get a lot more help that way
