Yes

In (3)...if load is changed why copper loss value not changed....?

[@mustafahajhamoud2077]

the copper loss value changes by x^2 if you are asking about the core loss, it doesnt change because it's directly connected to the input voltage V1 , so it's power is Pcore = (Vi ^2 ) / ( Rc) and Vi doesn't change with load changes

[@debasishmahanta8416]

@@mustafahajhamoud2077 The core/iron loss is independent of load condition as flux in the core remains constant throughout .
