When a short circuit occurs, why won't the light bulb light up as well? Since the short circuit and the main branch where the lightbulb is are connected in parallel so won't the two have equal voltages and hence the bulb will light up (P=V^2/R)? Some people told me that its because the resistance of the short circuit is alot lesser than the lightbulb. But it still has a value R right? If not wont the same thing happen if one branch has a R of 1ohm and the other with 10ohm, but we know something like this doesn't happen right? So I'm pretty confused here. Thanks for the help!
