Advantages of parallel circuits over series circuits are:
lights get progressively dimmer when more globes are added AND if one globe breaks, not all of them will turn off
lights remain the same brightness even when more globes are added AND if one globe breaks, not all of them will turn off
lights remain the same brightness even when more globes are added AND if one globe breaks all of them turn off
nothing
Primary differences be†ween series and parallel circuits are:
series - 1 loop
parallel - 2 or more loops
parallel - 1 loop, same current, divided voltage across component
series - 2 or more loops, divided current across loops, voltage the same across components
series - 1 loop, same current, divided voltage across component
parallel - 2 or more loops, divided current across loops, voltage the same across components
series - divided voltage across component
parallel - voltage the same across components
