Current is opposit flow of electrons and voltage is the
potencial differance between the two ends of the conductor.

Answer / jayanta

current:flow of electron
voltage:potential difference across two terminals of the
conductor

Answer / sujith

CURRENT: THE FLOW OF ELECTRONS THROUGH A CONDUCTOR.
VOLTAGE: THE FORCE THAT RISE ELECTRONS FROM -VE TO +VE
TERMINAL

Answer / himanshu joshi. (b.tech eee)

the rate of flowing of electric charge is current"
& the force of electron on which they flow is voltage.

Answer / vijin

current-- it is the flow of charge carriers through any
conducting medium. the direction of current is in
opposition with the direction of electron flow.
voltage-- it can be defined as the path or cause of passage
for the flow of current,that is the voltage or the
potential difference b/w two points is responsible for the
current flow.
more clearly the voltage at any point is the total
potential at that point when comparing with another point
or ground .this difference in the values of potentials will
force a current to flow from higher potential to a lower
potential.

Answer / vicky

current- rate of flow of electrons
voltage-rate of flow of current

Answer / prabakaran

current:
flow of electrons ,dangerous
voltage:
the force which tends to move the electrons ,less
danger compare with current

Answer / mandy

current-"the rate of flow of electric charge is current"
it's unit scalar

voltage-"it is define as the amount of electrons that flows between two points in a conductor at a given time"
it's unit is vector

Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
