Hello
I am taking introductory course in electronics and I am having some difficulties understanding some things.
The voltage source in a electronic circuits provides energy to drive electrones around the circuits which is what we call current.
How I see it :
In circuit A (I attached simple circuit drawing)
The current goes from the negative pole of the voltage source all the way through the resistor to the positive pole. And it keeps doing that untill the voltage source is emptied of its energy.
In circuit B I cant understand what is happening. How is the current supposed to reach the resistor ? The current goes from the negative pole and then meets a sign/symbol which I dont quite understand what is yet.
I believe this symbol is "ground"? But I havent yet understand what its purpose is.
Also I am confused with definitions with current/electrones and which direction they go in a circuit. I read in an article on the internet that by definition the elctrones in a circuit go from the negative to the positive pole, but the current goes from the positive to the negative pole.
However in my electronics fundamentals electronics course book the current is depicted in the circuit as going from the negative pole to the positive. What is correct? Did misunderstand ?
Any help is much appreciated
Thank you
