Answer / bijoy kumar soni

impedence of a transformer is defined by the vectorials sum
of resistance, capacitance and inductance of the core of
primary winding

Answer / gtr

resistance offered to the flow of current in the
transformer ckt which gives rise to thermal heating. for
efficent functioning, impedance is kept as low as
possible .

if the length, number of turns and area of coil are doubled then inductance of the coil becomes.?
