What does it mean to connect a circuit in parallel versus series?

Below picture is the easiest explanation.

Resistors R1 and R2 are connected in series, whereas R3 and R4 are in parallel.

For the current it means that the current through R1 and R2 is always equal, which is not the case for R3 and R4, there the current splits depending on the R value.

For the voltage it means that the voltage over R3 and R4 is always the same, regardless of the R value.

that line of code is written in the python programming language. put simply, a programming (or coding) language is a set of syntax rules that define how code should be written and formatted. thousands of different programming languages make it possible for us to create computer software, apps and websites.
