What is the difference between phase, neutral wire and
earth cable. if neutral is connected to ground, y we need
earthing cable? what difference in hot and cold wire? do
neutral wire carry current?

Phase- carry the current at required voltage..
neutral- negative phase of current vil flow through it..
Earth- the connection of ENTIRE neutral wires to ground..
we will not connect neutral n phase wire to ground...
Earthing cable s used for byepassing the current due to lightning,etc..
Neutral wire can carry current but it not real one.. dat s if u checkd with tester, there s no current in neutral it seems.. but actually it carries the negative part of current..
I dont know abt hot n cold wire.. if anyone knows pls post it

What is principle of Floroscent tube 36watt.
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
