Since, transfformer is a Static device (ie. no moving parts in it) hence it is the most efficient machines ever made by man.
However, in rotating machines there are various losses like friction and windage, losses in commutator etc.
So, yes, Transformers are highly efficient devices.

What will happen to the efficiency of a transformer if the iron core is removed?
its efficiency will decresed.
Disadvantages of IMPATT diodes?
Low efficiency
Why is primary coil in step up transformer thick?
A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.
How do you establish no of turns in both high voltage and low voltage windings of a 3 phase transformer?
Through the use of the basic transformer voltage equation.
What is a set down transformer?
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What is the efficiency of a transformer?
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
Describe why a high-efficiency machine is more desirable thana low-efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
Is the solar panels high low medium in efficiency?
Low
When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.
Why a high-efficiency machine is more desirable than a low- efficiency machine?
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
What is the condition for maximum efficiency of a 1-φ transformer?
The efficiency of a simple transformer is limited by resistive loss in the wiring, and by hysteresis (magnet related) losses in the transformer core. You may limit the resistance loss by using superconductors at very low temperatures. But not practical for most situations. (Yet!)
What is the purpose of a high voltage transformer?
if the transformer is distributing transformer then we shoud have to give more prefer to the high volatage to reduce losses if we distibute power at low volage there is more current which causes more losses and in hv system there is high volage and low is current so the losses are also low
Can you increase the efficiency of transformer by increasing the cooling of transformer?
nope
Is it always a good idea to discard low efficiency?
No...... Not always........... They can be modified to high efficiency..............
