Question 978328
Two electric bulbs each designed to operate with a 500 watts in 220 volt line are connected in series now they are connected with a 110 volt line what is the power generated by each bulb
---------------
P = E^2/R
R = E^2/P
R = 96.8 ohms
------------
In series, V across each bulb = 55 volts
----
P = 55^2/96.8
P = 31.25 watts
--------------
The bulbs don't generate any power, they consume it.
