Answer:

the secondary voltage is 60 V.

Explanation:

Given;

number of turns on the primary coil, Np = 100 turns

number of turns on the secondary coil, Ns = 300 turns

voltage supply in the primary coil, Vp = 20 V

let the secondary voltage = Vs

Apply the following transformer equation to determine the secondary voltage;

[tex]\frac{V_s}{V_p} =\frac{N_s}{N_p} \\\\V_s = \frac{V_p \times N_s}{N_p}\\\\V_s = \frac{20 \times 300}{100} \\\\V_s = 60 \ V[/tex]

Therefore, the secondary voltage is 60 V.
