2.8 explain why a series or parallel circuit is more appropriate for particular applications, including domestic lighting

Series and Parallel circuits:

Series circuit:

• All the components are joined in one line
• If the circuit is broken anywhere, all the components go off
• It is useful for powering thins e.g. fairy lights where the voltage needed is low
• Current is the same all the way round
• Voltage is shared equally amongst all the components

Parallel circuit:

• All the components are joined on a separate branch
• If the circuit on one branch is broken, the rest will continue, however, if the circuit is broken near the battery, the whole circuit will go off.
• It is useful for powering lighting in the home because you can turn only specific ones on which makes it very practical
• Voltage remains the same on each branch but is shared within each branch
• Current is shared so that the current on the main branch is the sum of the currents on the smaller branches
