$I=$ current in Ampere $($A$)$

$R=$ resistance in Ohm $()$

Series circuits have the following features:

The current is equal everywhere.

The total resistance is the sum of all resistances.

The sum of the individual voltage drops equals the source voltage.

Calculate the total resistance with:

$R_V=R_1+R_2+R_3$

Parallel circuits have the following features:

Each branch of the circuit receives source voltage.

The total current is the sum of the partial currents flowing through each parallel branch.

The total resistance is the source voltage divided by the total current.

Calculate the total resistance with:

$\frac{1}{R_V}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}$
