A common transistor radio set requires $12 V$ $(D . C .)$ for its operation. The $D . C .$ source is constructed by using a transformer and a rectifier circuit, which are operated at $220 V$ $(A . C .)$ on standard domestic $A . C .$ supply. The number of turns of secondary coil are $24,$ then the number of turns of primary are

Answer:

440.00

Solution:

$\frac{N_{P}}{N_{S}} = \frac{V_{P}}{V_{S}}$

$\frac{N_{P}}{24} = \frac{220}{12}$

$N_{P} = \frac{220 \times 24}{12}$

$N_{P} = 440$
