The copper losses of transformer at times the full load is proportional to times the losses at full load.
Hence at half the full load, the copper losses will be ((0.5)2 x 1600 = 400) Watts.

Ans 'd'
1)At full load pcu=i^2r i.e 400=i^2r
2)At half load pcu=( i/2)^2×r=i^2/4*r=400/4 =100w

Given: Full load copper-loss = 400W

To find: Copper-loss at half load

Explanation:

Copper-loss is the power loss due to the resistance of the transformer windings. It varies with the load on the transformer.

At full load, the copper-loss is given as 400W.

At half load, the current flowing through the windings is halved. Therefore, the copper-loss at half load can be calculated as follows:

Copper-loss at half load = (1/2)^2 x Full load copper-loss

Copper-loss at half load = (1/4) x 400W

Copper-loss at half load = 100W

Therefore, the copper-loss at half load is 100W.

Answer: Option A - 400W.
