Series wiring are type of connection in which, the loads are connected along a single path. It's an arrangement that, one end terminal of a load connects to end terminal of the next load in a sequence. And the two terminals of the supply line, will be connected across the end terminal of the first and last load in the sequence.

As the series wiring has all the loads in a single current carrying loop, the current through all loads will be same; current, I = V/(R1+R2+R3+R4… RN), but the voltage across the load are divided in proportional to its resistance.
Voltage drop across a resistor
The algebraic sum of the voltage drop across each load will be equal to the applied supply voltage. That is the total voltage distributes across each load and the net drop becomes equal to the supply voltage.
As Series connection has a single current flowing path, the loads can't be controlled individually. If one load is removed or damaged (enough to disconnect the line) the total circuit will become an open network.
