current common in series

Throw "constant" out. The word "constant" is time related. It does not apply to the "rule" you have in mind. If you change the voltage or the resistance the current will also change. Do NOT state "current is constant in series".

Current in a series circuit is _the same_ everywhere in the circuit. That is location related, not time related. Current will be the same at every point in the circuit at any given instant of time, whether the voltage or resistance varies over time or not. It is *far* better to say "current is _the same_ everywhere in a series circuit" than "current is _common_ in a series circuit".

Just say the current is the same at any given time in all parts of a series circuit.

Constant current implies a current source where the current is a constant when operating within the compliance range.
