Answer
The number of turns in the secondary coil (80 turns) is greater than in the primary coil (40 turns). This indicates that it is a step-up transformer.

Answer
Using the transformer equation:
rac{V_s}{V_p} = rac{N_s}{N_p}
Substituting the known values:
rac{V_s}{120} = rac{80}{40}
Therefore, the secondary voltage is:
V_s = rac{80}{40} imes 120 = 240 ext{ volt}
