The efficiency of a power plant is the ratio of output power to input power.
Efficiency is affected by factors such as fuel type, technology used, and maintenance.
Higher efficiency means less fuel is needed to produce the same amount of power.
Efficiency can be improved through upgrades and modifications to the plant.
Efficiency can be calculated using the formula: Efficiency = (Output Power / Input Power) x 100%
For examp...
Efficiency of transformer is the ratio of output power to input power.
Efficiency is an important parameter for transformers.
It is calculated as the ratio of output power to input power.
Efficiency is always less than 100% due to losses in the transformer.
Transformers with higher efficiency are preferred as they waste less energy.
Efficiency can be improved by using better materials and design.
For example, a transformer w...
