What is no load loss?
No-load loss is the amount of power (watts) used by a device such as a transformer or electric motor when it is connected to the power line but is not delivering any useful output. For example, if your doorbell is run from a transformer, it may consume, say, 3 watts continuously. This ends up as heat due to the heating of its windings, and the energy needed to magnetise the iron core. When someone presses the doorbell, it may draw 6 watts, 3 of them going to the bell to make it ring. Another example is an electric motor which is going round, but not driving anything. It may consume 100 watts, but its efficiency is zero. When it is driving, say, a machine tool it may consume 1000 watts, 900 of them being useful work in driving the machine.
