Hi Nanosy,

your bulb example is a good one as that's the major advantage of using parallel circuits. When you connect components up in parallel they are pretty much all separately connected to the power source (the cell/battery/mains) so if one bulb 'blows' all the others will still stay on ie each component/bulb is isolated. The disadvantage or parallel circuits is that the current is split between all the branches, which means that less electrons per second are moving through each bulb so less energy is transfered and the bulbs don't glow as brightly. The advatage of series is that all the current passes through each component, the disadvantage - that if one component breaks the entire circuit is broken. So burned out bulb in parallel chain is the (only) one that's off, in a series chain (like fairy lights) all will be off and you'll have to test each one with a new bulb.
