Quick intro

Parallel Circuits and Series circuit-

My way of remembering the differences :) 

I will tell you my way of remembering the difference between how to work out current and potential difference (P.D) 

If you already know this information and are looking for a more indepth resource, then feel free to leave :)

First stage

Series Circuit

So the acronym for Series circuit is (S.C)

This can be remembered as SAME CURRENT- 

Series Circuit Same Current!   (A1=A2=A3... )

So Current is the same between components in a Series Circuit, the name tells you already...


Current is measured in ampheres a.k.a amps

unit for current is A

Series Circuit

Now you know  current is the same between components in a Series Current...  it's obvious that potential difference will be the opposite XD

1) potential difference or also known as Voltage, is measured in Volts...  V

2) Potential Difference is shared between branches in a series circuit

V = V1 + V2... 

3 of 4

Parallel Circuits

Parallel Circuit...


Potential Difference  stays the same V1=V2=V3

So now you know potential difference stays the same, it's obvious current is shared...


Current  is shared between components...

 A=A1 + A2

Remember Series Circuit (S.C... Same current)... P.D shared

Parallel Circuit... P.. Potential difference same..... C... Current shared
