Circuits: You buy a set of Christmas lights in which 100 bulbs are connected in parallel with each other. The lights are connected across an ideal EMF source. Suppose 50 of the bulbs blow out. Which of the following statements is correct? The answer is: "The current through each of the remaining bulbs is unchanged." Why is that? Wouldn't the resistance be halved, therefore the current halved?

It's beacuse the bulbs are conectted parllel to the emf (battery) U r answer is right for series connection In parllel connection each bulb gets the same voltage and thus by ohms law thh same current With this connection the more bulb u connect u get the same currnt but the battery will be finished earlier! (if it is not a battery than u just pay more to the supplier...)
