The relationship between the number of turns in the primary (Np) and secondary (Ns) coils and the voltages in the primary (Vp) and secondary (Vs) is given by the following equation:
Vp / Vs = Np / Ns
Substituting the given values:
Vs = (Vp * Ns) / Np
Vs = (230 V * 500) / 100
Vs = 1150 V
The voltage in the secondary coil is 1150 V. Since the secondary voltage is greater than the primary voltage, the transformer is a step-up transformer. This is because the secondary coil has more turns than the primary coil, which increases the voltage.
