Answer / arun

flow of free electrons is called current..for flowing those
free electrons some pressure is important.so that is called
potential..so circuit should have a potential
difference...so that force of potential difference(voltage)
free electrons are moved in circuit....like this current
flows..

Answer / d devesh

if there is potential defference and the circuit is complete

Answer / mohan naik.b

current direction is always positive to negative TERMINAL.
but it is the direction of holes, which it is opposit
direction of electron flow.
Inotherwords we can say " higher potential to lower
potential in a given circuit."

Answer / taufic

In a closed circiut

Answer / anandan.g

by electrons movement, current flows through the conductor

Answer / tarun aggarwal ymca

when there is difference in potential the there is flow of
current through a medium that is used to carry the charge
between this potential.

Answer / chandan pandey , ballia

when voltage is apply in the ckt
we know voltage is a type of
electric pressure which press
electrons in the ckt in opposite
direction of flow of free electrons
current will be flow .

Answer / sidharth kapoor

current flow's from lower to higher potential.But when wee
say lower or higher potential in electronics context, :-0
what dose mean :-D ?

it means the number of positively charged atoms at the other
point which is 'B' of the conductor is more then with
respect to point 'A', and at point 'A' the negatively
charged atoms are more then positively charged atoms at
point 'A' so point 'B' sucks the negatively charged
electrons from point 'A'.

Potential difference can be controlled by the following:

Q1. How can i increase the potential difference ?

Ans1. increase the point 'A' side electrons
or increase the 'B' side atoms with positive charges i mean
(holes) or increase point 'A' side electrons and increase
point 'B' side atoms with positive charges(holes)


i hope it wipe great confusions.

Answer / gossa

EM waves do carry the energy to propagate the actual current at a rate which is much, much higher than the electrons' drift velocity

Answer / anonymus

it flows wen it feels like flowing..lol

armature is that part in which current is induced since in dc motor we supply current to the conductor so why we call it armature?
