A step-up transformer with 300 turns in the primary coil is supplied with 220 volts to this primary. How many secondary turns are needed to produce a 66,000 volt output?

Respuesta :

Answer:

Number of tuns in the secondary coil be 99000 volt.

Explanation:

Given that,

Number of turns in the primary coil, [tex]N_p=300[/tex]

Voltage of the primary coil, [tex]V_p=220\ V[/tex]

Voltage of the secondary coil, [tex]V_s=66000\ V[/tex]

Let number of tuns in the secondary coil be [tex]N_s[/tex]. It can be calculated using the turn and voltage ratio. It is given by :

[tex]\dfrac{N_p}{N_s}=\dfrac{V_p}{V_s}\\\\\dfrac{300}{N_s}=\dfrac{200}{66000}\\\\N_s=99000\ V[/tex]

So, the number of tuns in the secondary coil be 99000 volt. Hence, this is the required solution.
