Ohms law

Resistors in series
[tex]R_{eq} = R_1+R_2+...[/tex]
Resistors in Parallel
[tex]\frac{1}{R_{eq}} = \frac{1}{R_1}+\frac{1}{R_2} +...[/tex]
Current at nodes
[tex]I_{in} = I_{out}[/tex]
[tex]I_{total}= I_1+I_2[/tex]
Voltage from a power source is not distributed over parallel circuits, it remains constant
