Current Source
What is the source of the electrons in an electric current flowing through a circuit?
What is the source of the electrons in an electric current flowing through a circuit?
Electrons are in wires.But to flow electron it need e.m.f.Battery give a force to electrons to move in circuit.Electrons move very slowly in a circuit.But there are millions and millions of electrons and all start to move at same time and circuit conducts electricity

Eddy Current $152.95 An eddy current (also known as Foucault current) is an electrical phenomenon discovered by French physicist Franois Arago in 1824. It is caused when a conductor is exposed to a changing magnetic field due to relative motion of the field source and conductor; or due to variations of the field with time. This can cause a circulating flow of electrons, or a current, within the body of the conductor. These circulating eddies of current create induced magnetic fields that oppose the change of the original magnetic field due to Lenzs law, causing repulsive or drag forces between the conductor and the magnet. The stronger the applied magnetic field, or the greater the electrical conductivity of the conductor, or the faster the field that the conductor is exposed to changes, then the greater the currents that are developed and the greater the opposing field.The term eddy current comes from analogous currents seen in water when dragging an oar breadthwise: localised areas of turbulence known as eddies give rise to persistent vortices.Eddy currents, like all electric currents, generate heat as well as electromagnetic forces.

Lecture - 36 Current Source and Current Sink
Why is current source open circuited while voltage source open circuited ?
While applying superposition theorem why is current source open circuited and voltage source short circuited (when replacement by their internal impedances) to make it imoperable?????
Because a voltage source (ideal) is a voltage in series with zero ohms. Set the voltage to zero, and you are left with zero ohms, a short circuit.
A current source is a current in parallel with infinite ohms, so if you set the current to zero, you are left with infinite ohms, an open circuit.
