Series Circuits
 Components are connected from end to end
 Total resistance is the product of all the resistances added together
 If one component is removed or disconnected the circuit is broken
 Same current in all parts of the circuit
 Total voltage of the supply is shared between components
 The bigger the resistance of a component, the bigger its share of voltage
Parallel Circuits
 Each component separately connected
 If one of the components is disconnected then it does not effect those it is parallel with.
 All components get the full source voltage (therefore the voltage is the same in all the components)
 The lower the resistance of a component the greater the current
 Total current in the circuit is equal to the sum of the currents in its separate branches
 Total current going into a junction is equal to the total current leaving it
