Answer Posted / subba lakshmi
DC current should not be given to TFR bcoz in it frequency
is zero due to which the reactance which is given by
2*pi*f*l will be zero hence the entire voltage applied is
opposed only by the resistance fo the wire which is nearly
zero hence current produced will be high as v=I*R hence due
to which there are chances of melting wire.
