Answer / vijayakrishna

current: the flow of free electrons is called current.
current is flows when closed circuit is formed

voltageis defined as ths force required to move charged
particles(free electrons)from one point to another point.

power:the rate of change of energy is called power>

Answer / rajesh

talking practically current can be analogally feeled in
other way:
we take a tank which consists of water of some height.
we shall make some hole at the bottom.the bigger the hole
the smaller the resistance.
The definitions are here:
1)the disharge is known as current electrons/sec
2)the force applied on the bottom water is known as the
voltage
3)if you keep some hand at the hole you feel some force
which is power

electron moving current,
potential means voltage,
p=vi

Answer / majeed shoab

current is the flow of electrons during closing the circuit.
Voltage is the worke applied on wire to make the electrons
flow through it.
power is the force produced from multiplication of the
current by voltage.

Answer / anbarasu

power means high amplitudes of current and voltage
