Current in series circuits
A series loop gives electrons exactly one road, so wherever you station a meter along it, the reading never changes. What does change the reading is the supply voltage and how many components share the loop. This lesson works both dials and reads the effect on the current.
What you know already
Wire two lamps one after another and they share a single loop; wire them side by side and the current gains choices. This note follows the current through both arrangements — unchanging along a series loop, splitting and recombining at the junctions of a parallel network — with charge conservation as the bookkeeping rule behind it all.
Key points of understanding
- A series circuit offers a single loop, so electrons have only one path to follow.
- The current is the same at every point of a series loop.
- A larger supply voltage drives a larger current around a series circuit.
- Adding components in series raises the total resistance and so lowers the current.
- The current size depends on both the source voltage and the number and type of components.
The current is the same at each point in a series circuit
Current will increase if the voltage of the power supply increases and decreases if the number of components increases
