Given:
Full load copper loss (Pc) = 6400 W
Iron loss (Pi) = 5000 W

To find:
Copper loss and iron loss at half load

Solution:
Copper Loss:
Copper loss in a transformer is given by the formula:
Pc = Ic^2 * Rc
where,
Ic = Current at full load
Rc = Resistance of the copper winding

At half load, the current is halved. Therefore, the new copper loss (Pc') at half load can be calculated as:
Pc' = (Ic/2)^2 * Rc

Given that Pc = 6400 W, substituting the values in the equation:
6400 = Ic^2 * Rc

At half load, Pc' = (Ic/2)^2 * Rc

Dividing the two equations, we get:
Pc' / Pc = ((Ic/2)^2 * Rc) / (Ic^2 * Rc)

Simplifying the equation:
Pc' / Pc = (1/4)

Multiplying both sides by Pc, we get:
Pc' = (1/4) * Pc
Pc' = (1/4) * 6400
Pc' = 1600 W

Therefore, the copper loss at half load is 1600 W.

Iron Loss:
Iron loss in a transformer is constant and independent of the load. Therefore, the iron loss remains the same at half load.

Pi' = Pi
Pi' = 5000 W

Therefore, the iron loss at half load is 5000 W.

Conclusion:
The copper loss at half load is 1600 W and the iron loss at half load is 5000 W. Hence, the correct answer is option D) 1600 W and 5000 W.
