Dry type and oil type are two types of transformers based on the insulation used.
Dry type transformers use air as insulation while oil type transformers use oil as insulation.
Dry type transformers are safer and more environmentally friendly than oil type transformers.
Oil type transformers are more efficient and can handle higher loads than dry type transformers.
Dry type transformers are typically used in indoor applica...
Power factor is the ratio of real power to apparent power in an AC circuit. It can be maintained by using capacitors or inductors.
Power factor is a measure of how efficiently electrical power is being used
It is expressed as a decimal or a percentage
A power factor of 1 means all the power is being used efficiently
A power factor less than 1 means some power is being wasted
Capacitors or inductors can be used to correct po...

The second law of thermodynamics states that the entropy of an isolated system always increases over time.
Entropy always increases in natural processes
Heat flows from hot to cold
Efficiency of heat engines is limited by the second law
Entropy can be thought of as a measure of disorder or randomness
Examples: melting ice, diffusion of gases, irreversible processes
