Question

The number of turns of primary and secondary coils of transformer are 500 and 5000 respectively. The voltage and frequency of primary coil are 800 V and 50 Hz respectively, then the frequency and voltage of secondary coil will be (A) 50 Hz, 8000 V (B) 800 Hz, 800 V (C) 50 Hz, 80 V (D) 50 Hz, 800 V

(VS/VP)=(NS/NP) ⇒ VS=(NS/Np)× Vp =(500/500)× 800 =8000V No change in the frequency of transformer.

Q. The number of turns of primary and secondary coils of transformer are $500$ and $5000$ respectively. The voltage and frequency of primary coil are $800 V$ and $50 Hz$ respectively, then the frequency and voltage of secondary coil will be

50 Hz, 8000 V

800 Hz, 800 V

50 Hz, 80 V

50 Hz, 800 V

$\frac{V _{S}}{V _{P}} = \frac{N _{S}}{N _{P}}$
$\Rightarrow$
$V_{S} = \frac{N _{S}}{N _{p}} \times V_{p}$
$= \frac{500}{500} \times 800$
$= 8000 V$ No change in the frequency of transformer.
