Given:
First, we need to find the secondary voltage \( V_s \) using the turns ratio:
\( \frac{V_p}{V_s} = \frac{N_p}{N_s} \)
\( V_s = V_p \times \frac{N_s}{N_p} \)
\( V_s = 240 \, V \times \frac{1}{20} = 12 \, V \) ✨
Now, we can find the secondary current \( I_s \) using Ohm's law:
\( I_s = \frac{V_s}{R_s} \)
\( I_s = \frac{12 \, V}{12 \, \Omega} = 1 \, A \) 💡
Next, we find the primary current \( I_p \) using the turns ratio again:
\( \frac{I_p}{I_s} = \frac{N_s}{N_p} \)
\( I_p = I_s \times \frac{N_s}{N_p} \)
\( I_p = 1 \, A \times \frac{1}{20} = 0.05 \, A \) 🎉
Therefore, the primary current is 0.05A. ✅
