Question

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

Answer 1

$\Large\underline{\underline{\sf Given:}}$

• $\sf{V_1}$ = 120Volts

• $\sf{V_2}$ = 2400Volts

• Number of primary turns $\sf{N_p}$ = 75

$\Large\underline{\underline{\sf To\:Find:}}$

• Number of secondary turn $\sf{N_s}$ = ?

$\Large\underline{\underline{\sf Formula\:Used:}}$

$\Large{\boxed{\boxed{\sf \pink{\dfrac{V_s}{V_p}=\dfrac{N_s}{N_p}}}}}$

$\Large\underline{\underline{\sf Solution:}}$

$\implies{\sf \dfrac{N_s}{N_p}=\dfrac{V_s}{V_p} }$

$\implies{\sf \dfrac{N_s}{75}=\dfrac{2400}{120}}$

$\implies{\sf N_s=20×75 }$

$\implies{\sf N_s=1500\:turns}$

$\Large\underline{\underline{\sf Answer:}}$

•°• Number of secondary turns is 1500 turns.
