If multiple resistors in an electric circuit are connected in series, each of them is subject to Ohm's law. The current flows at the same rate through all resistors. The voltage, however, is not constant across each individual resistor.

These voltage drops sum up to a value that is equivalent to the external voltage applied to the electric circuit.
In the following two videos, we will first discuss the definition of a series connection and then provide a numerical example.
