Mini potentiometer

Naaah a bug u made so it reveal that u not ever check circuit if it is opertional grrr. Whenever i start read some interesting sentences at end whole dream about some freshy "knowledge gain for my brain" vainshes when by some ordinay foolish bug someone reveal that he even not try this circuit how it operstes cuz he himself propably do not handle operating it at all working here as live xero copy machine. How rightmost rheostat can be operated if it is hooked to VCVS as it will be operating a VCCS. I say one thing. A infinite input impedance voltge controlled device operated in way of forcing electric currents through infinite resistance using for this poor passive dirty hand controlled voltage to current converter called a rheostat ....WILL PERFORM VERY BADLY . Lol maybe when u try to etablish a current of one dollar bills a greedy VCVS will respond and u can have chance for a nice "chit-chat tet'a tet râñdë vü"

Thanks for your view. This circuit I made is just for theoretical explaination....No way for practical implementation. Just joined yesterday....let me get used to this.

Big plus for respond. Most ppl don,t even try to defend themselfs only asuring me in their intentions. As for practical implementation i asume that u not pay attention to dependent source type used by those who create this theory. Isn't it should be a CCVS ( lol now i reveal myself bugging when saying a VCCS it's wrong don't listen this guy above who write that) means current controled voltage source or simple transimpedance converter?? Only those can be directly controlled by rheostat . VCVS can be only controlled by pot as single element rheostat is unable to do so without at least one more resistor in circuit. (I have in mind lumped network point of view)

Thanks. I'll surely try your suggestion as soon as i understand this better.
