Answer / pinky

i think heat losses depends on impedance.

Answer / lalitha

imp Z= R+JX and T is direstly proportional to R...therefore
heat losses increase with imp

Answer / guest

Here heat losses
only consists of
Cu losses...and
it can be
denoted as
I2R....Cu losses
does not depends
on
frequency....so
heat losses will
vary only due to
change in
resistance..not
impedance...if
it is core
(iron) losses
then they r
definately
depends on
impedance Z...

Answer / nithi

Heat losses occur in resistance (real component) only ,not
in reactance(imaginary component).but heat losses depend on
the value of current flowing through the circuit (i.e.
I2).Meanwhile,current is decided by the impedance value
(reactance & resistance ). So,ultimately heat loss depends
on the impedance not only on resistance.
