Homework Statement
If two bulbs of power 25 watt and 100 watt each rated at 220 volts are connected in series with a supply of 440 volts. Which bulb will be fused?
The Attempt at a Solution
This is what I think I have to do-
Find out the resistances of each bulb from the data given.
Use P=I2R for each bulb and find out if it is greater than its power rating. The one with higher power rating will get fused.
Is this right?
