Suppose a piece of conducting wire is connected to one end of a power supply. Will the electrons in the wire respond to an electric field initially? How will they respond?
You know that eventually no current will flow in the wire. What is
the final configuration of the charge in the wire? Why does no
current flow? (this is called an open circuit)
What actually puts force on electrons to cause them to accelerate
in a complete circuit?
What happens if one section of a complete circuit is replaced with
a good insulator?
Homework Answers
electrons in the wire move as a result of the electric field which is generated due to the difference in electric potential at the two ends by the power supply. when only one end is connected to power supply , no electric field will be created but electron will realien themselves as per the polarity of power supply.
the charge in the wire remains the same with opposite charges being closer and like charges being farther placed. no current flows because there is no electric field to force the electrons from one end to other end.
The accelerating force inside the wire is created by the electric field inside the wire which in turn is produced by the difference in potential at the two ends.

Two parallel conducting rails a distance l apart are connected
at one end by a resistance R in series with battery of emf E. A
conducting bar completes the circuit, joining the two rails
electrically but free to slide along them. The whole circuit is
perpendicular to a uniform magnetic field B, as shown in (Figure

18[E]) When a power source like a battery is connected to a circuit, an electric field pushes electrons within the conducting wires causing them to flow. The electric field exists due to an uneven build up of charge on the surfaces of the wires (called a surface charge gradient). In this set of problems we will explore a simple model of how this all comes about and emphasize the connection between source charges, electric fields, and voltage differences in the...
