Question

What will happen to the brightness of a string of bulbs hooked up in series when you increase the number of bulbs in the string?

A. Each light in the string will get brighter.

B. Each light in the string will get dimmer.

C. There will be no change in the brightness of each light.

D. You cannot predict what will happen.

Answer 1

If I increase thye number of bulbs, then the current will decrease, so the power dissipated by each bulb will decrease, since the power W dissipated by each bulb is given by the subsequent formula:
\[W = R{I^2}\]
being R the resistance of each bulb

Answer 2

ohh so would choice B be the solution?

Answer 3

yes!

Answer 4

yay! thanks!
