Question

.A transformer that its number of turns in the primary coils is 200 turns, and 400 tuns in the secondary coil, if the supplied voltage difference is 10V, calculate the secondary voltage difference?

Answer 1

Applying the formula $\dfrac{N_P}{N_S}=\dfrac{V_P}{V_S}$

where N_p is number of turns in the primary coil and N_s is number of turns in the secondary coil

and V_p is the voltage difference in the primary coil and V_s is the voltage difference in the secondry coil

$\dfrac{200}{400}=\dfrac{10}{V_S}\\V_S=20 volts$
