What is the difference between the term Capacitance and Inductance?

Electrical and Electronic Engineering - Interview Questions

Difference between Capacitance and Inductance :

Capacitance : The term capacitance can be specified as an amount of charge stored inside a capacitor at a specifically given voltage.

Inductance : Inductance is the property of a coil to resist any changes in the electric current flowing through it. Mutual inductance happens when a secondary coil opposes the current change in the primary coil.

What are the advantages of VSCF wind electrical system?

Advantages of VSCF wind electrical system are :

* No complex pitch changing mechanism is needed.
* Aero turbine always keeps going at maximum efficiency point.
* Extra energy in the high wind speed region of the speed – duration curve can be extracted
* Significant reduction in aerodynamic stresses, which are associated with constant – speed operation.

Why electricity in India is in the multiples of 11 like 11kv, 22kv, 33kv?

Transformer Induced voltage equation contains 4.44 factor.

E=4.44*f*T*phi
E -Induced emf per phase
T -number of turns
f -frequency
phi -maximum flux per pole
From the equation we see that E is proportional to 4.4 and it is in turn multiple of 11.

So always transmission voltage is multiple of 11
