Answer 1

Please find the answer below:

At a certain dc current the energy stored in an iron cored coil is 1000j and its copper loss is 2000w. the time constant (in seconds ) of the coil is 1.0

This so because; E=pt

Answer 2

Answer:

and its copper loss is 2000w. the time constant (in seconds ) of the coil is
