Q15 of 33 Page 13

Do free electrons travel to region of higher potential or lower potential?

• A positive charge moves from a region of higher potential to a region of lower potential


• A negative charge moves exactly opposite, since the electron has negative charge. it travels from lower potential to higher potential

A parallel plate capacitor is connected to a battery as shown in Fig. 2.5. Consider two situations:


A: Key K is kept closed and plates of capacitors are moved apart using insulating handle.


B: Key K is opened and plates of capacitors are moved apart using insulating handle.


Choose the correct option(s).

Consider two conducting spheres of radii R1 and R2 with R1> R2. If the two are at the same potential, the larger sphere has more charge than the smaller sphere. State whether the charge density of the smaller sphere is more or less than that of the larger one.

 16

Can there be a potential difference between two adjacent conductors carrying the same charge?

 17

Can the potential function have a maximum or minimum in free space?
