Can a conductor store charge?
When analyzing circuits with resistors, inductors, capacitors, transistors, diodes batteries, etc connected together by conductors, you should assume that none of these circuit elements can or do store any charges. If you think charges can go into one side of a conductor without an equal number of charges exiting the other side of the conductor, you will find yourself very confused and unable to analyze any circuits or have any kind of intuitive feel for how circuits work.

In real life, any object which is surrounded by a dielectric can possibly acquire a net charge (by various methods), and therefore experience electrostatic attraction or repulsion, but charge storage is not an important concept in circuit analysis. 

Please note that we sometimes say that capacitors or batteries "store charge," but this is not true in the sense you are asking about. Every time a mobile charge flows into one terminal of a capacitor or battery, another one flows out the other terminal. For any circuit element with two terminals, the current flowing in is equal in magnitude to the current flowing out instantaneously at all times.

Otherwise, we would not be able to use KCL to analyze circuits.
