Question

The number of turns in the primary and the secondary coils of a transformer are 1000 and 3000 respectively. If the primary of the coil is connected to 80 volt ac, then potential difference per turn of the secondary coil is :

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

Answer 1

The correct option is D 0.08 V

we know that $\frac{e_s}{e_p}=\frac{N_s}{N_p}$

$\frac{e_p}{e_s}=\frac{N_p}{N_s}$

$\frac{80}{e_s}=\frac{1000}{3000}$

so $e_s=240V$

Potential difference per terns $=\frac{240}{3000}=0.08$
