I download ebook

Books is very nice.

I also start to read.
But I am confuse the following sentence
(Chapter 2 , Page No. 2.23, 3rd Paragraph)

" For the same power, the motor can be wound with half the number of turns and the current is halved."

How become current is halved?
Can any one derive the same?

I think it is may be oversite/mistake of printing.

It may be " the motor can be wound with doubling the number of turns and the current is halved."

Pls. let me know from expert engr.

Thanks

Bhalkar,

You are right.
It is printing mistake.

correct answer is " For the same power, the motor can be wound with twice the number of turns and the current is halved."

Thanks

It may also be: the motor can be wound with half the number of turns and the current is doubled.
