If a step-up transformer has a primary coil with 15 turns, how many turns would be required in the secondary coil in order to increase the voltage from 80 volts to 160 volts? A. 8 turns B. 30 turns C. 80 turns D. 160 turns

Respuesta :

Answer:

[tex]N_2=30turns[/tex]

So option (b) will be correct option

Explanation:

We have given that there is a step up transformer in which number of turns in primary coil is 15

That is, [tex]N_1=15[/tex]

Primary voltage [tex]V_1=80volt[/tex], and secondary voltage [tex]V_2=160volt[/tex]

We have to find the number of turns in the secondary \

We know that for the transformer

[tex]\frac{N_1}{N_2}=\frac{V_1}{V_2}[/tex]

[tex]\frac{15}{N_2}=\frac{80}{160}[/tex]

[tex]N_2=30turns[/tex]

So option (b) will be correct option
