Why is current the same everywhere in a series circuit?
A series circuit have only one conducting path and then, for reasons related to conservation principle of total charge, the total current at input is in every instant equal to the total current at the output (and NOT "...the same everywhere...").

Current is the same everywhere in a series circuit because there is only one path for the flow of electrons. Therefore, the same amount of current must flow through each component in the circuit.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
