Lesson 1 of 2
Voltage in series & parallel
One battery, two very different sharing habits. In a single loop the components divide the voltage between them, with the greedier resistor taking the bigger share. In parallel, every branch is wired straight across the supply and takes the whole voltage. This lesson compares the two arrangements side by side.
What you know already
In a series loop the battery's voltage is divided among the components; in a parallel network every branch receives the full supply. This note works through both divisions, explains why identical series components split the voltage equally, and weighs which arrangement suits a real job better — including why homes wire their lighting in parallel.
Key points of understanding
- In a series loop the supply voltage is shared out among the components.
- Two identical components in series take equal shares — half the supply voltage each.
- With different resistances in series, the larger resistance takes the larger voltage share.
- Every branch of a parallel circuit receives the full supply voltage.
- Components wired in parallel therefore all see the same voltage across them.

Lamps connected in a series circuit share the potential difference from the battery
