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.
