Efficiency of a Transformer
The efficiency of a transformer can be calculated using the following equation:
Efficiency
The efficiency of a transformer can be increased by:
*Using low resistance windings to reduce the power wasted due to the heating effect of the current.
*Use a laminated core which consists of layers of iron separated by layers of insulation. This reduces heating in the iron core and currents being induced in the core itself (referred to as eddy currents).
