Question

two light bulbs, one 25 W and the other 100 W, are connected in series to a 120 volt battery ( all three circuit elements are in series). In this situation (choose one of the following defend your choice with an explanation):
A) the current in the 100W bulb is greater than that in the 25 W bulb
B) the current in the 100W bulb is less than that in the 25 W bulb
C) both bulbs will light with equal brightness
D) each bulb will have a potential difference of 60 volts
E) the current in the 100 W bulb is equal to that in the 25 W bulb

Explanation / Answer

in series combintion of resistance , same current exists across each of the component, np matter what the wattage an element in a circuit has, it can have only the resultant manitude of current in it. E) the current in the 100 W bulb is equal to that in the 25 W bulb
