Please answer the following two questions, thank you.

**Transformer Calculation** An ideal transformer has 1500 turns and 75 turns in primary and secondary coils respectively. If 10.4 amps flows in the primary side, what is the load current? --- To solve for the load current in an ideal transformer, we can use the formula: \[ \frac{I_p}{I_s} = \frac{N_s}{N_p} \] Where: - \( I_p \) = primary current - \( I_s \) = secondary current (load current) - \( N_p \) = number of turns in the primary coil - \( N_s \) = number of turns in the secondary coil Given: - \( I_p = 10.4 \) amps - \( N_p = 1500 \) turns - \( N_s = 75 \) turns Substitute the known values into the formula to find \( I_s \): \[ \frac{10.4}{I_s} = \frac{75}{1500} \] Solving for \( I_s \): \[ I_s = \frac{10.4 \times 1500}{75} \] Calculate \( I_s \): \[ I_s = 208 \] amps Thus, the load current is 208 amps.
