Transcription: In this lesson, we will discuss current flow in a series circuit. Resistors may be connected in a circuit in series or parallel. If the voltage source is connected within the ring or loop containing the resistors, the resistances are connected in series, hence the name series circuit. If the voltage source is placed external to the loop, the result is called a parallel circuit. Let's first discuss current flow in the circuit. There are two important points to consider when discussing current flow in a series circuit. Number one, there is only a single path for current flow. Consequently, the s ...
