Answer / sai krish

Movement of electrons from one place to other place is said
to be flow of current. Whereas voltage is the potential
difference between two terminals.

Ex: When a lamp does not glows when connected across
circuit, it means no flow of current. If glows, current
flows via the circuit.

Answer / ganeshkumar1453

let us consider a tank at up stairs
when u open the valve water flows.we know that flow of water is regulated by valve .
Then here current is water.
tank is certain height na that is potential i.e., voltage
and valve is resistance

Answer / hardyparvaiz

the relation is V is inversely propotional to current
I, the variable factor between then is power factor which
changes them accordingly

Answer / elango.k

current means the rate of flow of electrons.
voltage means the pressure applied to move the electrons

Answer / saurabh srivastava

V=IR i.e. ohms law which states that when the current
applied to any conductor is directly propotional to the
potential diff. across its ends keeping physical terms
constant is used to relate between current and voltage.

Answer / lakshmi prasanna

according to kirchoff's current law.voltage and current has
directly proportional relationship at constant temperature.
defintion of current is the rate of flow of electrons.
where as definition of voltage is the workdone in moving a
charge carrier from one point to other againt the field.
there exists a potential difference can be called as
voltage.

Answer / vinoth

The movement of electron is current..

The force which makes electron to flow is called voltage..

Answer / raseelrasheed

example,if water is flowing from bottom(bottom) to tank
(top) with help of pumpset,we know that water cannt flow to
top without help of ext. power.here the functions are

comparison
WATER-workdone--electrone
PUMP -force--battery(voltage source)
TANK -load---bulb
so the functions of voltage is supply power for dead
electrone to climb valance region and to blow the bulb
