the current in series will be same..
Yes, the current is the same at every point in a series circuit.
Kirchoff's Current Law: The current at every point in a series circuit is the same. This can also be expressed as the sum of the currents entering a node is zero. Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero.
A series circuit has the same amount of current at all points in the circuit.CommentIt's not simply 'the same amount of current at all points''; it's the same current at all points.
Nothing about a series circuit is necessarily constant. You may be thinking of the current, which is the same number at any point in a series circuit. That doesn't mean that it can't change. But if it does change, it'll change at every point, and still be the same number everywhere in the series circuit.
