Series and parallel circuits

SERIES CIRCUITS

• If you remove one component, the circuit is broken, and everything stops working.

• The current is the same anywhere in a series circuit.

• The voltage in a series circuit will split between the components.

• The sum of voltages across components is equal to the voltage of the supply.

• If multiple components are in series, voltage divides equally between them.

PARALLEL CIRCUITS

• If you remove one component, it will not affect components on a different ‘branch.’
• The current will split down each strand.
• The voltage is the same anywhere in a parallel circuit.
