Question

A wire carrying $5.0V$ is applied to a transformer. The primary coil has $5$ turns and the secondary coil has $10$ turns.

• A. $0.50V$
• B. $5.0V$
• C. $10V$
• D. $50V$
• E. $100V$

Answer 1

The correct option is C $10V$

Given : $N_p=5$ turns $N_s=10$ turns $E_p=5.0$ V

Using $\frac{E_s}{N_s}=\frac{E_p}{N_p}$

OR $\frac{E_s}{10}=\frac{5.0}{5}$ $⟹E_s=10$ V
