Series And Parallel Circuits

Series Circuit

All parts connect in a single loop ( one path for charges to flow )

Parallel Circuit

Different loads are on separate branches ( allowing charges to flow in more than one route )

Ohm’s Law

V = I x R

Voltage

How much energy each electron has flowing through the circuit.

Voltage Sources

Battery, Generator, Outlets
