# a short circuited is placed in atime varying magnetic field. electrical power is dissipated due to the current induced in the coil. if the no of turns were   to be quadrupled & the wire radius halved the electrical power dissipated would be

Dear student,

The emf induced in the coil=
Hence power dissipated in the coil=
Hence when number of turns is quadrupled and radius halved, the power becomestimes its initial value. Hence the power dissipated does not change.
