Question

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

• A. $240V$
• B. $24V$
• C. $0.24V$
• D. $0.08V$

Answer 1

The correct option is D $0.08V$

Potential difference across each turn $\frac{{\text{V}}_{\text{s}}}{{\text{N}}_{\text{s}}}=\frac{{\text{V}}_{\text{p}}}{{\text{N}}_{\text{p}}}=\frac{80}{1000}=0.08\text{V}$
