in a series circuit, the electrical current is only able to flow around a single path. the current will flow from a power source, such as a battery, into one or more electrical loads, such as a light bulb, and then back to the power source. in a series circuit, the same amount of amperage from the power source flows through each load. the voltage in a series circuit is divided up across all of the loads. if one of the loads on a series circuit stops working, the current will not be able to flow through the rest of the circuit, and the rest of the loads will also stop working.
