The number of turns in the primary and the secondary of a transformer are 1000 and 3000, respectively. If 80 V AC is applied to the primary coil of the transformer, then the potential difference per turn of the secondary coil would be (a) 240 V (b) 2400 V (c) 0.24 V (d) 0.08 V

Answer: (d). Vs = Vp (Ns)/(Np) = 80 × (3000)/(1000) = 240 V Voltage per turn = (240)/(3000) (same as (80)/(1000) for the primary) So the answer is (d) 0.08 V.

AC Generator & Transformer

The number of turns in the primary and the secondary of a transformer are 1000 and 3000, respectively. If $80\text{ V AC}$ is applied to the primary coil of the transformer, then the potential difference per turn of the secondary coil would be

Show answer and solution

Answer: (d)

$V_s = V_p \frac{N_s}{N_p} = 80 \times \frac{3000}{1000} = 240\text{ V}$
Voltage per turn $= \frac{240}{3000}$ (same as $\frac{80}{1000}$ for the primary)
So the answer is (d) $0.08\text{ V}$ .
