Statement (A) : In high current low voltage windings of a transformer thick wire is used to minimize energy loss due to heat produced Statement (B) : The core of any transformer is laminated so as to reduce the erergy loss due to eddy currents.

Pendulum after some time becomes slow in motion and finally stops due to
