Remove the Rows section (anchor names are documented on Template:Rt)

Conrad: Row anchors as zero-height blocks above the image, so a row link shows the whole table

The '''Series Circuits''' box from the ''Reference Tables for Physical Science: Physics'' (2025 Edition) gives the three rules for components connected in series. It primarily supports [[HS-PS3-6]], together with the [[Electricity]] equations and the [[Parallel Circuits]] box.

== What the series circuits box shows ==
In a series circuit there is one path for the current, so the current is the same through every component; the potential difference of the source is shared, so the potential differences across the components add up to it; and the equivalent resistance is the sum of the resistances, so adding a resistor in series raises the total resistance and lowers the current. With [[Electricity#ohm|''V'' = ''IR'']] these rules give the current and the potential difference across each component.

== Rows ==
Each row of the table has an anchor, so a link or an <code><nowiki>{{Rt}}</nowiki></code> chip ([[Template:Rt]]) can point at one equation or constant:
* <code>series-current</code> – ''I'' = ''I''1 = ''I''2 = …
* <code>series-voltage</code> – ''V'' = ''V''1 + ''V''2 + …
* <code>series-resistance</code> – ''R''eq = ''R''1 + ''R''2 + …

== Regents Exam Questions ==
Released Regents questions that cannot be answered without this table, listed by exam. Each link opens the question with its answer key; the standard is the one the question assesses.
