A step-up transformer is used on $120 V$ line to provide a potential difference of $2400 V$ . If the number of turns in the primary is $75$ , then the number of turns in the secondary shall be

Options:

Answer:

Solution:

$\frac{N_{s}}{N_{p}} = \frac{V_{s}}{V_{p}}$

$\frac{N_{s}}{75} = \frac{2400}{120}$

$N_{s} = 1500$
