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.

The height of the tower can range from 15 meters to over 50 meters depending on the above factors.
For example, in hil...
CT and PT can be differentiated visually in substation by their size, shape, and labeling.
CTs are typically larger and cylindrical in shape, while PTs are smaller and more rectangular.
CTs are often labeled with a ratio, such as 100:5, while PTs are labeled with a voltage rating.
CTs are usually located on the high voltage side of the substation, while PTs are on the low voltage side.
CTs are used to measure current, whil
Single phase induction motor works on the principle of electromagnetic induction.
It has a stator and a rotor.
The stator has a single phase winding which produces a magnetic field.
The rotor is either squirrel cage or wound type.
When AC supply is given to the stator winding, it produces a magnetic field which induces a current in the rotor.
This current produces a magnetic field in the rotor which interacts with the stato...
