Answer / sambi reddy

power transform theorems says ;i/p power = o/p power.
it dosent mean that power will be electrical .
there is power ; megnetic power & losses.
the ip power is 1150w at i/p side and linking flux is
depend on the number of o/p side turn and we get 12w as o/p.
just like
i/p power= total o/p power
i/p power= o/p electrical power+ o/p megnetic power+ losses
(copper & iron losses).

The Maximum Power Transfer Theorem states that the maximum
amount of power will be dissipated by a load resistance if
it is equal to the Thevenin or Norton resistance of the
network supplying power.

The maximum Power is transfer to the load,Whenever the input
and output impedance is matched.

We have to consider the impedance of that pfimary and
secondary side.

Differentiate between microcontroller and microprocessor.
