Answer / rakesh

Current is nothing but the rate of flow charge through the
conductor. Voltage is nothing but the potential between the
terminals.

Answer / a v prasad

CURRENT: rate of flow of charge in a conductor dq/dt

VOLTAGE: work done to move a unit charge . dw/dq

Answer / gowrishankar shanmugam

current:
The rate of flow of free electrons from one terminal to
another terminal when an external force is applied.

voltage:
The force applied to move the electrons is called
voltage. It does the work. It also referred as potential.

Answer / rilip kumar

Current is the speed of electron & voltage is the pressure of electron.The controlled movement of electron is called current & the potential difference between two end of conductor is called voltage.

Answer / bhagya

current:Flow of electron in a specified dirction

voltage:to take that flow of electrons from one end to
another end

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 ?

I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)
