Expert Answer:

Dear student,

If we want to connect two bulbs to the same battery then an obvious way to connect them is in series.  The problem with connecting two bulbs in series is that both bulbs are dim and if you turn one bulb off then they both go off.

At home all your appliances are connected in parallel with each other.  This means they all get the full mains voltage and you can turn on your TV without having to turn on your microwave as well.

There are two advantages of connecting bulbs in parallel.

  1. They all get the full battery voltage so they're all bright
  2. They're all in their own conducting loop so you can turn one bulb off without affecting the others.

Hope this helps.
