A closed surface S is condtructed sround a conducting wire connected to a battery and a switic (figure 30-Q6). As the switch is clsed, the free electrons in the wire start moving along the wire. In any time interval, the number of electrons entering the closed surface S is equal to the number of electrons leaving it. On closing the switch, the flux of the electic field hrough the closed surface

A

is increased

B

is decreased

C

remains unchanged

D

remains zero.

An imaginary closed surface P is constructed around a neutral conducting wire connected to a battery and a switch as shown in figure. As the switch is closed, the free electrons in the wire start moving along the wire. In any time interval, the number of electrons entering the closed surface P is equal to the number of electrons leaving it. On closing the switch, the flux of the electric field through the closed surface :

If the flux of the electric field through a closed surface is zero,

If the switch is closed then current will flow.
